ComparePDF - Compare PDF text and visual changes priv

ComparePDF is a free online PDF comparison tool that helps users identify text and visual differences between two versions of a document. Review contracts, reports, and scanned PDFs using side-by-side, overlay, slider, and difference views.

All processing happens locally in the browser, so files are never uploaded or stored on a server. No account is required, and English OCR can help detect text changes in scanned documents. ComparePDF supports PDF files up to 25 MB each and is designed for fast, private document review.
