Best free PDF editors: Our top picks

While nothing beats a full-featured PDF editor like Adobe’s Acrobat Pro DC, sometimes you don’t need all the bells and whistles. When you just have to edit a few lines of text, add or reposition an image, or make some review notes, a free PDF editor may be the way to go.

Free PDF editors offer a few advantages over their paid partners. First and most obviously, they don’t cost anything. If you don’t work regularly with PDF files, a premium editor probably won’t be worth the investment and a free editor can get the job done on the occasions you need to make some quick changes to document. Second, free PDF editors generally work in your browser so, unlike paid PDF editors, there are no platform- or device-compatibility issues to worry about. (The exceptions are free trial versions of paid editors, which need to be downloaded to a device.) Finally, because free online PDF editors are used on-the-fly, they generally have much simpler, more-intuitive interfaces and tools than paid editors do.

Of course, you can’t expect a free product to have all the sophisticated features of a paid one. Most will let you edit PDF files by adding and modifying text and images and annotating with shapes, freehand drawings, and notes. Fonts and font sizes, colors, and shape options will almost assuredly be more limited than what you’d find in a paid editor, though. Free editors will also let you create PDFs and convert them to other file formats. This is probably all you need for occasional work with PDFs.

You may find features like form filling, e-signatures, and content redaction in some free editors. But capabilities like password protection and bates numbering are almost unheard of. Frankly, if you dive deep enough into PDFs to use any of these features, you’re probably better served by one of the desktop editors in our best paid PDF editors buying guide.

What to look for in a free PDF editor

• Content editing: As its name indicates, a PDF editor’s primary function is to enable you to edit a document. That includes the ability to add and modify text; insert, resize, and move images; and reorganize pages in the PDF. Most free PDF editors will let you perform these tasks, though they may impose daily limits on how many you can perform or how many documents you can edit.
• Create, convert, and export PDFs: A common need for a PDF editor is to create PDF files from scanned hard copies or by converting digital documents. A good free PDF editor will be able to convert common file formats such as Word, JPG, and HTML to a PDF and preserve the original formatting. It should also be able to export PDFs into other editable formats such as Microsoft Word and PowerPoint, HTML, or plain text, maintaining the original files hyperlinks, images, and other elements.
• Review and annotate: Most free PDF editors allow you to add comments and other annotations to PDF files during review. Typical annotation tools include sticky notes, shapes, and drawing markup options.
• Signatures: Often all you need a PDF editor for is to sign a document. This used to be a premium feature only available on paid desktop editors, but more free PDF editors are allowing users to create and add electronic signatures to documents.
