You can visually compare two PDFs in Acrobat, but for automation, use the Adobe PDF Services API as described here.
The Adobe PDF Services API provides a Compare operation that programmatically compares two PDFs and returns a diff PDF or change data.
The 'Compare text only' option means Acrobat will only look for changes in the words. It will ignore any pictures or other graphics in the documents. This is useful if you only care about text changes, like in a legal document or a report with many images.
The 'Compare Files' tool fails with a security message because one or both of your PDF documents have protection settings. These settings stop Acrobat from making changes or comparisons. To fix this, you must first remove the security from the files before you can compare them.
Yes, you can use 'Compare Files' to see differences between signed and unsigned documents. Acrobat has a specific feature for comparing signed document versions. This helps you check if anything changed after a document was signed. You can find more details on how to use this for signed documents in the help section.
