See exactly what changed between versions

Contracts, drawings and reports change between drafts, and it's easy to miss an edit. Compare PDFs puts each page of the two versions side by side and marks every area that changed in red, so you can spot added words, moved images and altered numbers at a glance. The note tells you which pages changed.

Private by design

Compare PDFs runs entirely in your browser. Your file is processed on your own device and is never uploaded to a server, there's no sign-up, and the result is ready to download as soon as it's done.

Questions

How does it compare the files?

It compares how each page looks, so changes in text, pictures, tables and layout all show up.

What if the files have a different number of pages?

Extra pages are shown next to an empty space and counted as changed.

Which sensitivity should I use?

“Normal” suits most documents. “Big changes only” ignores tiny differences from re-saving or scanning.
