Supported languages

compares existing Unicode text in any language, including Urdu and Arabic, when the PDF contains correct text mappings. It does not translate or recognize scanned text. Scans need OCR first, with the OCR tool’s separate language limits.

How to use compare pdf text

  1. 1. Select the original and revision

    Choose exactly two PDFs together: original first, revised second. Check the displayed order.

  2. 2. Compare existing text

    Select Compare text. Scanned pages require OCR before they can be compared.

  3. 3. Read the differences

    Review the before-and-after text for changed page positions and download the report. Check images and formatting separately.

What this tool preserves

Text comparison only. Images, formatting and moved pages are not analyzed. OCR scanned documents first.

Privacy and practical limits

Files stay on your device. Each input must be under 150 MB. Processing speed and memory use depend on your device. Keep original documents; PDF transformations do not preserve digital-signature validity.

The report names both files and shows the original and revised text for each changed page position, including added or removed pages.
