About Compare PDF
Compare PDF shows what changed between two versions of a document. Text differences and visual changes are highlighted page by page, so you can check a revised contract, review edits to a report or spot layout changes in a design proof without reading both files line by line.
Frequently asked questions
Compare two PDF files online and highlight differences in text and page visuals. See added, removed and changed content side by side – free and private.
What kinds of changes are detected?
Added, removed and changed text, plus visual differences in page content.
Do both PDFs need the same number of pages?
No. Extra or missing pages are reported in the comparison.
Are my files uploaded?
No. Both PDFs are compared in your browser.
Can I compare scanned PDFs?
Visual changes are still highlighted, but text comparison needs real text. Run scans through PDF OCR first for better results.
Which file should I add first?
Add the original version first and the newer version second, so additions and deletions are labeled the right way round.
