How do I compare two versions of a PDF?
Drop both documents: pages are placed side by side and the areas that differ are highlighted. Handy for finding what moved in a contract reviewed by several people.
Compare PDF
Spot what changed between two versions of a document.
Drop the old and the new version. Each page is set against its counterpart and you get back a review document: both versions side by side, changed areas highlighted. The comparison works on appearance, so it catches layout changes too.

Common questions
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
