Eight PDF apps for Mac, side by side.
We make Sheaf, so we’ve tried hard to be fair: facts about other apps come from their own websites, checked 13 November 2026, and linked below. Prices change; their sites have the final word.

“Where files are processed” is what each company’s site says or shows. If a site doesn’t say whether its desktop app works offline, we haven’t guessed.
Pick by the job, not the brand.
Compress, merge, sign, convert: Sheaf does them where you drag the file. Preview handles the basics for free.
Editing the words in a PDFChanging paragraphs or building fillable forms is Acrobat’s and PDF Expert’s home turf. Sheaf doesn’t edit existing text.
Preview is built in. PDFgear is free with more tools. Sheaf keeps 3 actions a day free after its trial.
UPDF and Acrobat cover every platform with one account. Sheaf is Mac-only.
Contracts, IDs, statements: use an app that works on your Mac rather than uploading to a website.
Sheaf is one purchase. PDF Expert and UPDF also sell lifetime licences. Acrobat and Smallpdf are subscriptions.
Sheaf
A menu bar app: start dragging a PDF, pause, and actions open around your cursor. Compress, merge, split, sign, redact, OCR, convert, page numbers, watermarks, PDF to Excel and more, each in about a second, all on the Mac. Not for: editing existing text, annotating while you read, Windows or iPhone.
Apple Preview
Free and already installed. It reads PDFs well and can merge (via thumbnails), sign, fill forms, rotate, redact by hand and reduce file size with a filter that often blurs text. Not for: page numbers, watermarks, OCR you can save, Word conversion.
Adobe Acrobat
The most complete PDF editor, with text editing, form building and e-signature workflows. It’s a subscription: Standard is US$14.99 a month on an annual plan, Pro US$19.99 (Adobe’s US prices). Overkill if you mainly compress, merge and sign.
PDF Expert
A polished Mac reader and editor from Readdle, sold as a yearly plan or a one-time Lifetime licence for Mac, on the Mac App Store. Strong for reading, annotating and editing.
PDFgear
Free, with a long tool list and AI features (“PDFgear AI”), for Mac and the web. Its site doesn’t say which features run on your Mac and which online.
UPDF
An editor for Mac, Windows, iOS and Android under one account, with yearly or lifetime licences. The free version adds trial watermarks to edited, annotated or protected files; AI features are an extra subscription.
Smallpdf and iLovePDF
Popular browser tools: nothing to install, so they’re handy on a borrowed computer. You upload the file to their servers, and free use is limited. Smallpdf is billed annually per user; iLovePDF has a free plan with per-task limits and a Premium plan that adds a desktop app.
