Compare PDF

Comparing two PDF documents side by side allows you to visually check differences between versions, verify changes, or review revisions. Our Compare PDF tool renders both documents simultaneously, with independent page navigation for each document.

This is invaluable for reviewing contract revisions, verifying that exported documents match originals, or checking formatting differences between versions. Each document is rendered at full resolution using pdfjs-dist for clear, readable previews.

All rendering runs client-side in your browser, ensuring your documents never leave your device. You can navigate through each document independently with easy-to-use page controls. The service is free with no registration.
