Compare PDFs
Open two PDFs side by side, browse matching pages, and review added or removed text. All processing stays in your browser.
Compare extracted text while viewing both PDF pages
Select two PDF documents to view each page side by side. You can navigate paired pages, see extracted-text differences and download a change report. This tool cannot certify that scanned images, signatures, graphics or layouts match; OCR is needed for scanned text.
What happens to my PDF?
The document never leaves this browser tab for this tool. Your device performs the work with locally hosted PDF components. No login is required. We collect limited technical events but not document contents.
Can I use this tool on a mobile phone?
Yes, for compatible PDFs. Very large files and scanned pages may be slower or run out of memory on older devices. For heavy conversions, a desktop browser may be more comfortable.
