You can filter the comparison results to focus on text, images, or formatting changes for a clearer review.
This runs in the Acrobat app - there is no separate API for this task.
The 'Compare text only' option tells Acrobat to ignore all images and graphics in your PDF files. It will only look for differences in the words. This is useful when pictures change but the text is most important, making the comparison faster and clearer for text-focused documents.
This message appears because one or both of your PDF files are protected. Security settings can stop Acrobat from reading the files fully, which is needed for comparison. To fix this, you must remove the security protection from the documents before trying to compare them. This ensures Acrobat has full access.

This helps you check if anything was altered after signing, without invalidating the digital signature. The comparison focuses on content, not the signature's integrity.
