Though it’s nearly 25 years old, the PDF may be more useful than ever in our increasingly multi-device, cross-platform world. Much of the time you can get by with a free PDF reader to review and comment on these files. But inevitably, particularly in a business setting, you’ll need to edit a PDF file and that usually requires upgrading to a premium PDF editor.

Historically, Adobe Acrobat has been the best option, but it has also been the most expensive, often putting it out of reach of individuals and small businesses. That has given rise to a wealth of alternatives with varying features and costs. We looked at six PDF editors to see what they offer and how they stack up against each other.

Updated 1/11/19 to include our review of PDFelement Pro 6, which delivers hassle-free PDF editing, and is a compelling, low-cost alternative to Acrobat. See the bottom of the page for a list of all our PDF editor reviews. 

Acrobat Pro DC's comprehensive PDF features show why it's still the editor against which all others are judged.

Adobe Acrobat Pro DC remains the industry standard for good reason. Its rich combination of creation, editing, reviewing, and security features are what the best alternative options are built on, but we feel Acrobat still does it best. Its recent interface redesign makes it much easier to navigate its robust toolset than the nested menus of yore, and its cloud subscription option puts its advanced features within reach of more individuals and small businesses.

Nitro Pro 12 is an excellent PDF editor that will streamline your document workflow.

Nitro Pro 12 bumps its previous version, Nitro Pro 11, for the runner-up spot. Its now full integration with Nitro Cloud—as part of Nitro Productivity Suite—makes collaborating on documents and securing signatures easier than ever. The ability to perform common editing tasks right in a browser rather than having to toggle over to the desktop program makes document workflows feel simpler and more seamless.

PDF Architect 6 Professional is an affordable business-ready Acrobat alternative that doesn't sacrifice performance for price.

This customizable PDF editor comes in several different flavors, each with its own set of “modules,” or tools, so you can purchase only those you need. But even the Professional edition, which has a near complete tool set, only costs $109. You sacrifice little for that affordability, as it includes plenty of review, collaboration, and security features. (Read our full review.)

Why spend a chunk of change on a desktop editor when free online PDF editors abound? The simple answer is because you get what you pay for. Generally, free online editors will let you add text and comments, merge and split documents, and convert files to and from PDF. With rare exception, however, they won’t let you edit existing text and many have file-size and page-volume restrictions. And a lot of them will watermark your edited document. For these reasons, web PDF editors are best reserved for simple, fast editing jobs. Call in these big dogs for anything more demanding.

One of the great things about a PDF is that it can be read and edited in any PDF program regardless of which one it was created in. So beyond the features outlined here, let your personal preferences guide you in making your decision.

If you want to learn more about all of the PDF editors we reviewed, see the list below. We’re kicking off our guide with six PDF editors, but we’ll continue to evaluate more as time goes on—as well as re-evaluate those we’ve already reviewed.
