Why use our Compare PDFs
Secure & private
Files are encrypted in transit and deleted automatically after processing.
Fast results
Optimized processing returns your file in seconds.
Free to start
Core tools are free with daily limits — no install required.
Works anywhere
Runs in your browser on any device, anywhere in the world.
Never re-read a contract twice
When a counterparty returns "the same document with small changes", comparison shows you exactly where those changes are — instead of you re-reading 40 pages hunting for them.
What comparison catches
Text edits, additions and deletions between the two files. It works best on text-based PDFs; scanned documents should go through free OCR first so there is text to compare.
Typical users
Lawyers checking contract redlines, buyers verifying revised quotes, editors confirming requested corrections, and anyone asked to "sign the updated version". Files are processed temporarily and deleted automatically — there is no general cloud storage.
