Frequently asked questions about PDF comparison tool

Does it compare scanned text with OCR?

No. Image-only text is not recognized or compared by OCR.

Will it show pixel-level design changes?

No. The result is a text-based report of readable text and page-size differences.

What if the PDFs contain the same words in a different layout?

Review the report together with the original pages, because layout changes may not be represented as a visual diff.

Does the tool change my original file?

No. Both source PDFs remain unchanged; the tool produces a comparison report.

Can I use it with a password-protected PDF?

A protected PDF may need to be unlocked before the tool can read or process it.

Will large files take longer?

They can. Processing time depends on the file size, page count, and the work required for each page.
