Compare Two PDFs

Compares the readable text of two PDFs, page by page, and shows what was added or removed: red for text removed in the second file, green for text added. Pages are matched up automatically, even if pages were inserted or deleted.

About Compare PDFs

Compare PDFs by Scalebar is a browser-based tool that compares two PDF versions and automatically identifies their differences. Text documents are compared page by page, highlighting added and removed text, while architectural drawings are compared visually at the pixel level to reveal graphic changes. Pages are matched automatically, even when pages have been inserted, removed or reordered, and the comparison can be exported as a PDF report.
