Best practiceFor best results, avoid using scanned PDFs as input files, as text recognition may be inconsistent.
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 Files feature might not work if one or both of your PDF documents have security settings. These settings can stop Acrobat from looking inside the files to find differences. To fix this, you need to remove any security protection from both PDF files before you try to compare them again. You can usually do this in the document's properties or by using a 'Protect' feature if available.
The 'Compare text only' option tells Acrobat to ignore any pictures or graphics in your PDF files and only look for differences in the words. This is useful when you only care about text changes, like in a written report, and don't want to be distracted by small changes in images or layout that are not important to you.
Acrobat has a specific way to handle signed documents. When you compare signed document versions, it can show you if the document was changed after it was signed. The comparison tool is designed to help you manage digital signatures and see what changed between the signed version and another version, without invalidating the signature itself. This helps maintain the integrity of important documents.
