So verwendest du PDF Compare
Upload two PDF files and the tool compares them locally in your browser. It checks whether the binaries match exactly, compares file size, page count, page dimensions, metadata like title/author/dates, and any fillable form fields it can detect. This makes it useful for revision checks, form template audits, and spotting structural changes without sending the documents to a server.
