PDF Compare: Compare Documents

PDF Compare shows you exactly what changed between two versions of a PDF.

Got a contract back with "a few small edits"? A revised agreement, a new policy, an updated quote? Pick the original and the revised copy, tap Compare, and every difference is marked for you. No more reading two documents side by side and hoping you caught everything.

EVERY CHANGE, IN ONE LIST
• Added words in green, removed words struck through in red
• Reworded text shows the old and new wording together
• Each change shows the sentence around it, so you know what it means
• Tap any change to jump straight to it on the page

MARKED ON THE REAL PAGES
• See the revised copy with new wording highlighted
• Flip to the original to see what was taken out
• Step through the changes one by one with the arrows
• Pinch to zoom on any page

OVERLAY FOR SCANS AND DRAWINGS
Scanned pages and drawings have no text to compare, so Overlay lays the two copies on top of each other. Anything only in the original shows in red, anything only in the revised copy shows in green.

SAVE A MARKED-UP REPORT
Save one PDF with a summary of every change, then both copies with the changes highlighted. Open it, print it or share it with your lawyer, client or team. The text in the report stays real text, so you can still search and copy it.

PRIVATE AND OFFLINE
Your files never leave your phone. Everything is compared on the device, with no upload and no account. It works with no internet at all.

ALSO
• Opens password protected PDFs (you type the password, it stays on the phone)
• Choose whether capital letters and punctuation count as changes
• Line breaks and spacing never count, so text that only moved to a new line is not flagged
• Share one or two PDFs straight into the app from any file manager or email
• Try it in seconds on the built in sample contract

Every feature is free. A one time purchase removes the ads.

Recent changes:
First release. Compare two PDFs and see every added, removed and reworded word, marked on the page. Overlay for scans, a marked-up PDF report, and it all runs offline.
