Compare Two PDFs Side by Side

Open two versions of a PDF and see exactly what changed between them. Differences are highlighted so you can spot edits, additions, or deletions at a glance.

This is invaluable for reviewing contract revisions, checking proof iterations, or verifying that a "final" document actually matches the approved draft. Save yourself the tedium of reading both versions line by line.

Frequently Asked Questions

How does the comparison work?

Pages are rendered as images and displayed side by side. You can visually spot differences between the two versions.

Does it compare text content or visual appearance?

Visual appearance. Each page is rendered and shown next to its counterpart. This catches layout shifts, font changes, and image differences.

Can I compare PDFs with different page counts?

Yes. Extra pages in the longer document are shown alongside blank placeholders.
