Best free PDF editors 2023: Their top picks

If you work with PDF files regularly then a PDF editor is an indispensable tool. Whether it’s part of your job, you manage PDF files for your own personal use, or you just need to complete a one-off editing task, a top editor program is an essential piece of software. Full-featured editors such as Adobe’s Acrobat Pro DC might provide all of the bells and whistles, but a free PDF editor can still offer most of the important tools of a paid service for no additional charge.

Plus, many free PDF editors are browser based, which means that you don’t need to worry about about platform- or device-compatibility issues.

Of course, free products won’t come with every feature of their premium counterparts. So, if you find that you need more advanced tools such as password protection, Bates numbering, or e-signatures, then you’re probably better served by a premium PDF editor.

PDF Candy – Best free PDF editor overall

Pros

Cons

Price When Reviewed: Free

PDF Candy is the rare free PDF editor that offers a lot of the features you’d typically have to pay for. We’re talking scanning, multiple file-conversion options, and OCR functionality. While the free version has access to the expansive toolset of the paid version, you’re limited to one PDF task per hour. For unfettered access, you need to shell out $6 month.

Apple Preview PDF editor – Best free PDF editor for Mac users

Pros

Cons

Price When Reviewed: Built into macOS

Mac users have an excellent PDF editor built right into their operating system. Although its ostensibly a photo viewer, macOS’s Preview app is rife with PDF-editing capabilities including tools for adding text and shapes, redacting content, making freehand drawings, inserting sticky notes, and capturing your signature using your trackpad, camera, or iPhone.

Sejda PDF editor – Most versatile free PDF editor

Pros

Cons

Price When Reviewed: Free (Premium $7.50/mo)

Offered as both an online tool and a desktop editor, Sejda is capable of performing dozens of tasks including editing, form creation and filling, Bates stamping, file encryption, and more. If the daily usage limits are too restrictive for you, you can upgrade to the affordable paid version.

While there are a number of different types of PDF file formats, they all fall under the umbrella term of PDF documents. A PDF form is a type of PDF document that has editable form fields a user can fill out. Typically, parts of the document are static and can’t be changed in a PDF form. These usually include questions and instructions for those who end up filling out the form later on. In a PDF form, the content fields a user fills out are typically open to editing and can offer a list of possible answer options or can be written in freely.

Yes. They are two entirely different document formats. While you can export from one file format to another, they are not the same. Word file formats are usually used for word processing, editing, and making changes to text. PDF documents on the other hand, are most often utilized for viewing, sharing, and printing documents. Additionally, Word files can be read and/or written to and contain some version of the “.doc” file format. Whereas PDF files are typically read-only and contain the “.pdf” file format.

Yes. If you have a PDF document that you do not want anyone else to be able to edit, you can protect the file. You can do this by opening the file in Acrobat, clicking Tools > Protect. Then you have a few options as to whether you want to just restrict editing with a password, or if you want to encrypt the file for further safety. Once you choose how you want to protect the PDF document, you can set a password and save.

Yes, many free PDF editors such as their top pick PDF Candy, allow you to merge two or more PDFs into one. As most free PDF editors are browser-based, you will just need to open up the PDF editor application or website in your browser and click the “Merge” option. It will then ask you to add the files of all PDFs you wish to merge. Once the files have been added, just make sure that they are in the correct position and alignment you want before proceeding with the merge. Afterwards, all of your previously PDF files will be merged together into one new PDF document.

Yes and no. Google doesn’t provide a designated free PDF editor itself, but there are third-party Chrome extensions that you can use to help get the job done. Alternatively, you can make use of Google Drive to edit a PDF document. Simply upload the document onto your Google Drive and then select the file and right-click and select Open with > Google Docs. The file will be opened as an editable Google Docs text document. Then just make your edits and when you’re finished click File > download > PDF Document to revert it back to a PDF file.

This method is a quick and easy way to edit a simple PDF document, but be careful as Google Docs can run into formatting issues if your original document has complex visual formatting such as tables and graphs. In this case, it’s best to use a designated free or premium PDF editor.

The best PDF editors for 2023

The PDF file format has great support for text and video, as well as an efficient file size, making it a great format for all kinds of documents and data. It’s also excelelnt for preserving the quality and formatting of a document.

Adobe Acrobat is perhaps the most well-known PDF editor, but there are other options to consider. Having access to a PDF editor opens the possibility of editing document texts, adding images, filling out forms, and converting your PDF files to other formats. A PDF editor is a useful tool if you work with this format regularly.

Our guide to the best PDF editors will help you choose the right editor for your needs.

Adobe first introduced the PDF format nearly 30 years ago, and Acrobat Pro DC is the current industry standard for editing PDF files. It’s a PDF editor that combines the hallmarks of the other programs on their list into a unified piece of software. It’s also one of the few premium programs available for both Windows and MacOS. Acrobat Pro DC boasts dedicated mobile functionality (with iOS and Android apps) and the ability to convert various file formats to PDF, including multiple web pages (HTML), Word documents, Excel spreadsheets, PowerPoint presentations, and even scans or image files like PNG or JPEG.

Simply put, you can’t do much better than the premium version of Adobe Acrobat Reader for editing your PDF files. It has an array of text-editing options, and can instantly convert and save scanned documents to PDF. It even has the ability to merge multiple PDF files. Adobe’s editing options also include reordering pages, page rotation, annotations, page cropping, page removals, and being able to split PDFs into separate files.

If you use Microsoft Office, then you already have access to a versatile PDF document editor.

In the past, versions of Microsoft Word were limited to saving a document in or out of the PDF format, and that was about it. However, the more accurate 2013, 2016, 2019, 2021, and Microsoft 365 versions allow you to open a PDF and then make specific edits to the piece as a Word document. When finished, you can save it as a PDF again. This is especially useful because many people are already most comfortable editing documents in the Microsoft Word format.

It’s a simple tool, and formatting doesn’t always line up correctly based on the PDF, but it’s an excellent alternative if you need to dip into a PDF fast for a bit of basic editing or text changes. Plus, Word is a straightforward editing tool for employees and students who are already familiar with Word and don’t want to learn a new program.

While there are limited ways you can use Microsoft Word for free, it is generally software that you have to pay to use, either via a subscription or a hefty one-time payment.

German company Pdfforge has a unique purchase model for its PDF Architect program. It’s available as a free download or as part of three separate packages (Standard, Professional, and Pro+OCR).

Professional features all the modules from the Standard package and adds the Review/Comment, Secure, and Forms modules.

Sejda is a web app designed for speedy PDF editing, and it does that very well. It’s straightforward, focusing on fast PDF signatures and only basic text editing for the files you upload. But that’s also why they like it. This online, free PDF editor lets you do all sorts of things to PDFs, including changing font formatting, adding images, filling out forms, adding or editing hyperlinks, adding form fields, making annotations, and signing PDFs. You can even sign a PDF file with three options: Drawing your signature with your mouse, typing in your name, or uploading an image of your signature.

It provides explicit instructions, making it hard to mess anything up, and it’s quick. If your boss or co-worker doesn’t really understand how to use technology or have the patience to download new apps — but you still need their signature on a random PDF file — this is one of the best ways to e-sign a document.

If you’re looking for an easy online PDF editor, then give this one a shot. The free version does come with some limitations, however: You can only upload up to 200 pages or 50 Mb and you can only do three “tasks per hour.”

Depending on which premium plan you select, the desktop version can cost $3 or $6 per month (when billed annually), but you can test them out with a free trial. Luckily, you won’t need an internet connection to use the premium desktop versions, and $3 to $6 a month isn’t too bad. Overall, it’s a functional, simple PDF editing tool. If you aren’t looking for anything too complicated, give it a try.

Foxit PDF Editor is a great premium option for businesses and professionals that need more editing tools.

Best free PDF reader (2023)

The best free PDF reader apps are perfect for viewing documents, collaborating online, and making changes to your PDF files without any subscription charges or one-off fees. 

Using your browser is the easiest way to read a PDF online, but options are usually limited. To do more with your documents, both online and offline, it’s worth investing time in the best PDF editors, the best free PDF editors, or dedicated PDF reader software. 

PDF readers are the ideal solution for casual users looking for easy-to-use apps and platforms. Better still, the very best free PDF readers come equipped with plenty of tools for power-users. So, look out for features like free PDF to Word converters that put you in control of your documents. 

With plenty of options out there, it can be a challenge identifying which free PDF reader is best for you. To help you find the right tool for your work, we’ve tested out a range of options, exploring everything from performance with large files to cross-platform compatibility and the best cloud storage integration.  

Best free PDF reader overall

Operating system: Windows, macOS

Multi-platform support

Handles large PDFs with ease

Tab view for multiple documents

Relatively large

Regular 'upgrade to Pro' ads

Some tools paywalled

Adobe Acrobat Reader DC is a free PDF reader software for Windows and Mac (with Android and iOS PDF reader apps available, too). And it's their top choice for best free PDF reader overall - although they found features one massive downside.

The top PDF viewer is designed with two purposes in mind: the first is to enable you to read and interact with PDF files (including adding annotations and even signing a document). 

The second is to convince you to upgrade to the paid version of the software (which, you’ve guessed it, has many more features, including the ability to create and edit PDF files).

If it wasn’t for the latter, Acrobat Reader would be a decent addition to your software library. It’s simple, easy to use, and comes with all the basic features you need to interact with PDF files. In their review, they reckoned that “Adobe Acrobat Reader DC is one of the best free PDF readers for anyone looking to view documents and manipulate them in some way.”

Sadly, the adware side of things is pretty much everywhere: you get ‘try now’ buttons, you’re offered to use powerful tools but later are asked to pony up some cash in order to actually use them, there’s even a ‘7-day trial’ button. If you can overlook this, it’s a great tool, but there are less obtrusive ones out there.

Best free PDF reader for wide platform support

Operating system: Windows, macOS, Linux, Android, iOS, Citrix

Allows you to create PDFs

Safe mode disables Javascript

Lightweight download

Some features require extensions

No OCR in free version

Foxit PDF Reader is more than just a free PDF reader – you can also create PDFs from scratch using this software. Integration with Microsoft Office allows you to easily turn documents you’re working on into PDFs. Or, you can scan a document or image and turn it into a PDF using Foxit Reader. The only thing that’s lacking in the free version is support for optical character recognition in scanned documents.

The software can be a little intimidating at first, but it’s relatively straightforward to navigate. That’s thanks to the fact that it uses the same ribbon-style menu as Microsoft Office. Tools for editing, signing, highlighting, and commenting are fairly easy to access. You can also merge or split PDFs by downloading free add-ons for the software. 

Another advantage to Foxit PDF Reader is that it offers security. There’s a Safe memorizing mode that allows you to automatically disable Javascript embedded in downloaded PDFs.

Note that with the software's latest update, Foxit seems to have removed its PDF virtual printer driver, meaning you can no longer use the software to create PDFs.

Best free PDF reader that's fast and lightweight

Operating system: Windows, macOS, Linux

Small download size 

Loads extremely quickly

Can convert file types

No editing 

Not many features overall

Slim PDF is the best free PDF reader if you’re looking for something incredibly lightweight. The software download is really small, so is the perfect choice if you’re limited by hard drive space. Plus, that means that it’s able to open and load your documents faster than most of its competitors.

In their review, they called it "a sleek, minimalist PDF reader that only takes up a couple of megabytes on your hard drive." The downside to this small size is that Slim PDF is pretty basic. You can search and rotate documents, but that’s about it. 

And you have to go in knowing that. Slim PDF feather-light when it comes to features. If you're looking for a PDF editor, you won't find it here. Nor will you find tools for signing, filling, commenting, or highlighting, let alone multiple memorizing modes. This application reads PDFs plain and simple, cut and dry. 

While there is a menu option to convert a PDF to a Word document, doing this requires another software download. On the other hand, if your needs are similarly simple, the free PDF reader might just be the solution for you.

As a result, Slim PDF is truly just a PDF reader. It does a good job at this, though, leaving out the toolbars that can distract you from what you’re reading. If you frequently need to print PDFs, Slim PDF is one of the fastest and most simple options available.

Best free PDF reader that's feature-rich and packed with tools

Operating system: Windows, macOS

Touchscreen mode 

Plenty of annotation tools

Simple ribbon-style menu

No document signing or filling

Lacks advanced features found in Nitro Pro

The Nitro PDF Reader is another powerful free PDF reader in the vein of Foxit Reader and Adobe Acrobat DC. What makes this tool different is that it has a touchscreen mode that’s perfect if you’re working on a tablet. Touchscreen mode is especially nice for memorizing e-books, since you can flick the pages rather than scroll or click on a button.

While you can’t fill and sign PDFs with Nitro Reader - this is, after all, a pared back version of Nitro's Pro PDF editor, with no OCR or the ability to insert, remove,  and reorder pages) - it remains an excellent tool that will make everyday document-wrangling much easier.

The software does a nice job of enabling collaboration. You can annotate documents with underlining and strikethroughs in addition to highlighting. Comments are also supported, and they appear like sticky notes that are easy to spot as you read through a document. Helpfully, the software also allows you to convert between PDF and other document formats.

The software has a ribbon-style menu that will be familiar to Microsoft Office users. The menu is pretty easy to navigate since there aren’t all that many options available in Nitro Reader. Overall, they found the app to be a remarkably powerful free PDF reader that's packed with handy features you'll use time after time, all presented in a clear, adaptable interface.

Perfect if you need a free PDF reader with built-in OCR

Operating system: Windows

Optical character recognition

Text editing

Splits and extracts pages

Free version watermarks documents

PC-only

Rather than just being a free PDF reader, PDF-XChange Editor is also a free PDF editing program for Windows. The interface is a little more complex than some others but gives you easy access to plenty of helpful features. 

For most users, the main reason to use PDF-XChange Editor is the fact that it comes with inbuilt Optical Character Recognition (OCR). This means that if your original PDF document is a photocopy, PDF-XChange will still recognize the text and allow you to edit it. Also, PDF-XChange Editor lets you reformat text, and even convert it into fonts that aren’t already loaded on your computer. You can use this platform to merge or split individual PDF files. 

It's not the perfect free PDF reader, however. There is one big, unignorable disadvantage to using the app: it'll stamp a 'Created with PDF X-Change Editor' watermark on any PDF file you export. That disappears once you sign up to the Pro version, but it's still an issue that's going to put some people off. 

During their tests, they ultimately felt that while nothing stood out as incredible, there was also nothing that stood out as frustrating or annoying either. Under the right circumstances, it's a great product that has the ability to be your one and only PDF editor without any compromise.

Best free PDF reader for viewing only

Operating system: Web, Windows, Mac, iOS, Android

Cross-platform with apps for online, on Windows, Mac, iOS, and Android

Customer support is responsive

Plenty of editing tools

No sign-up to read PDFs

Full toolkit  requires subscription

Advanced tools may prove steeper learning curve than most

pdfFiller serves up a very simple free PDF reader experience. If your needs are basic, it’s quick and easy to upload your document and read it via your browser, or through the Windows, Mac, Android, and iOS apps. Not only is the PDF viewing process free, you won’t even need to sign up to read files. 

However, the platform is actually a full PDF editor, with plenty of additional features for document creation and editing like fillable forms, data redaction tools, online collaboration, digital signatures, and PDF converters. After a thorough review process, they ultimately felt that the platform is “a very versatile PDF document management system” for both personal and business use. 

When it comes to a straight PDF viewer, pdfFiller’s free service feels hobbled by the inability to do anything beyond memorizing files. You can tweak documents, but they’ll remain locked on your dashboard and unavailable as a PDF file. To really get the most from the service - and, to be fair, it offers a fair amount - you’ll need to subscribe to one of three monthly/annual subscription plans. Enterprise licensing is available, too, for teams of ten or more.

When deciding which PDF reader is best to download and use, first consider which parts of your PDF file you need to change. If you’re just trying to add information to a form digitally, you’ll only need a basic editor that supports text insertion.

However, if you need to change the content of a PDF substantially, you’ll require a more powerful PDF software program that can make modifications to text or images already stored in the file. In some cases, especially if you want to change almost all the content of your file, it may be better to use a fully functioning PDF Editor or even the best PDF to Word converter instead.

A PDF reader is a program used to open, view, and print PDF (Portable Document Format) files. First introduced in the 1990s, PDF files are an excellent way to distribute documents containing text, images, and various other media types.

Many modern browsers can read PDF files, but the best free PDF readers still have their place. These dedicated programs give users more ways to interact with the file and offer greater control over how the document appears on the screen.

PDF files were designed to appear and function the same on any piece of hardware, so you'll find PDF readers for Android and other mobile devices too.

Deciding between a PDF editor and a PDF reader comes down to how you'll use the software. PDF readers are primarily designed to view documents - although many include online collaboration tools like commenting, highlighting, and annotating content. Altering a PDF file is often limited to small edits and manipulation. A PDF editor lets you design and create documents from scratch and make large changes. They almost always include powerful tools for power-users, like built-in OCR software and digital signature tools. 

If you keep your computer secure and download PDF software from the official source, you should be well-protected. But, as with many free tools, there are always risks. We've outlined five common reasons why free PDF editors may not be right for your organization - and the issues can be similar with free PDF readers. We've also looked at the main differences between paid-for vs free PDF editors. 

The best free PDF readers feature plenty of tools for viewing and sharing PDF files - however, they're often slightly more limited compared to paid-for counterparts. In many cases, they offer a taste of how the software works, with upgrades and subscriptions that add more tools. If you're only memorizing PDFs on your computer or mobile device, a browser will likely meet your needs. If you're frequently in and out of documents, making minor edits, and sharing files, a full PDF reader will likely suit you best. 

We test the best free PDF readers against the factors that users care about - from the interface and experience to performance and platform availability.

We also assess each tool against its use-case. Some want a lightweight reader, others need one packed with plenty of other PDF utilities for professional use - so they look at how well the free PDF readers deliver for their intended audience. 

We also ensure that free means free - no hidden charges. Any subscriptions, lifetime licenses, and upgrade fees must be clearly signposted. 

As part of their overall testing process, we've also reviewed and rated free and premium platform-specific PDF readers.
