Compare PDF: what it is and when to use it

Spot the differences between two versions of a document.

Comparing two PDFs shows you what changed from one version to the next: text added, removed, or modified. It saves you from reading both documents line by line to find differences.

Choose the original and the new version, and Rayo PDF GO points out the differences page by page, without sending the documents to any server.
