This message means that one or both of your PDF files are protected. Security settings stop Acrobat from comparing them. To compare the files, you must first remove the security protection from both documents. You can usually do this in the 'Protect' tool if you have the right permissions.
| Setting | What it does |
|---|---|
| Autodetect Mode | Acrobat automatically figures out the best way to compare your documents, looking at both text and graphics. This is good for most files. |
| Compare text only | Acrobat only looks for changes in the written words. It ignores any pictures, drawings, or other visual elements. Use this when you only care about text edits. |
No, comparing signed document versions will not affect the signatures themselves. The 'Compare Files' tool is designed to show you what changes were made between the versions. It helps you see if any content was altered after a signature was applied, but it does not modify or invalidate the digital signatures. You can use a special feature to compare signed documents.
