Best practiceIf either PDF is a scanned image, use Acrobat's OCR feature first to convert it to searchable text for more accurate comparison.
Save or export the comparison report if you need documentation of the detected changes or potential plagiarism.
You can click any highlighted change in the results to view the exact difference side-by-side in the document.

Yes, Adobe Acrobat has a special feature to compare versions of signed documents. You can use the 'Compare signed document versions' option. This lets you see changes made before and after a signature was added, or between different signed versions. It helps ensure the integrity of the document's content even after it has been formally signed.

To fix this, you need to remove the protection from both documents first. You can usually find options to manage document security under the 'Protect' tools in Acrobat.
| Setting | What it does | When to use it |
|---|---|---|
| Autodetect | Acrobat tries to find all changes, including text, images, and layout. | Most common choice for general document comparison, like a curriculum with text and diagrams. |
| Compare text only | Acrobat only looks for differences in the words and numbers. It ignores pictures and graphics. | When you only care about text revisions, and changes to images or formatting are not important. |
