Open Adobe Acrobat on your computer.

The Compare Files feature fails if your PDF documents have security settings. These settings stop Acrobat from reading the files properly to find differences. To fix this, you must remove any passwords or other protections from both files before trying to compare them.
The 'Compare text only' option tells Acrobat to ignore pictures and other graphics. It will only look for changes in the written words. This is useful if you only care about text edits and not visual changes.
When you compare signed document versions, Acrobat will show you the differences between them, even after they were signed. This helps you track any changes made after the signing process. You can see what parts of the document changed and when.
