Compare PDFs

Find what changed between two versions of a PDF: changed words and changed pixels, page by page.

Open Compare PDFs

How it works

1. Drop the original PDF and the new version.
2. See each page marked identical, text changed, or visually different.
3. Open a page to see old, new and the changes in red; download a side-by-side PDF.

Good to know

• Compares text and rendered appearance. Very small visual changes can be missed.
• Free with no limits, accounts or watermarks. Files are processed in your browser and never uploaded.

Questions

Can it compare scanned PDFs?

Visually yes. Text comparison needs real text, so run OCR on both first.
