TL;DR: PDF Expert edits, signs, and converts PDFs on Mac without a subscription — PDF Expert Premium Plan is on sale for $79.99 (reg. $139.99).
Adobe Acrobat charges a recurring monthly or annual fee just to edit, sign, or convert a PDF, and that bill keeps arriving whether you open the app once a week or once a year. PDF Expert charges a one-time fee for a lifetime license to the Premium plan for Mac, on sale for $79.99 (reg. $139.99).
PDF Expert is built specifically for macOS, so it opens fast and runs cleanly on Apple silicon rather than feeling like a Windows app ported over.
Editing includes fixing typos, updating numbers, inserting images, and adding links directly inside a PDF. Annotation tools add highlights, sticky notes, and custom stamps for reviews. Organizing a document means merging multiple files into one, reordering or rotating pages, and splitting a PDF into separate files.
Document conversion runs both directions, turning PDFs into Word, Excel, or PowerPoint files and turning JPGs, PNGs, or Office documents back into PDFs. Forms can be filled out and signed in a few clicks, sensitive information can be redacted before sharing, and OCR makes scanned pages searchable and copyable.
One-time signatures also allow someone else to sign a document without first setting up their own PDF Expert account.
License activation applies to unlimited personal Mac devices running macOS 12.0 or later, and ongoing support and bug fixes are included, though major new features down the line may cost extra.
Verified user ratings run 4.6 out of 5 on both the Apple App Store and Capterra, with PCWorld and TechRadar close behind at 4.5.
This deal is limited to new PDF Expert users, and codes need to be redeemed within 30 days of purchase.
