View two PDF documents side-by-side with synchronized scrolling to quickly identify what changed between versions. Perfect for comparing contract revisions, legal document drafts, report versions, or any document where you need to identify differences between two iterations. No files are uploaded — both PDFs are rendered locally in your browser.
Contract negotiations often go through multiple revisions. The differences between version 3 and version 4 of a contract may be subtle — a changed clause, a removed liability cap, an altered payment term. Side-by-side comparison lets you review both versions simultaneously with pages aligned, making it far easier to spot changes than alternating between two open documents. Legal teams, procurement departments, and editors all routinely use PDF comparison to catch unauthorized or unintended changes between document versions.
The tool provides a synchronized side-by-side view for visual comparison. Scroll both documents in sync to compare pages directly.
No. Both PDFs are rendered locally in your browser using PDF.js. Your files never leave your device.
Yes. Documents with different numbers of pages can be compared — pages align as long as content is present on both sides.
Upload the original as the left document and the revised version as the right document. Scroll through systematically, focusing on clauses you know were under negotiation.
