Compare Extracted Text - Free Online Browser Tool

Diff-check text content between two document versions.

For legal and editorial review, what matters is usually the words, not the layout. This tool extracts the text from both documents and reports precisely where the wording differs, which is the fastest way to check what a revision actually changed.

How to Use the Compare Extracted Text Tool

Four steps, and the whole thing runs locally on your own device.

  1. Add the original and the revision

    Drop in both versions. Order matters: the first is treated as the baseline.

  2. Extract text from both

    The text layer of each document is read and compared word by word.

  3. Review the differences

    Changed, added and removed passages are highlighted, with the page each difference occurs on.

  4. Export the report

    Download the difference list to circulate as a change summary.

Frequently Asked Questions

Why does a text diff show nothing when the layout clearly changed?

Because this tool compares words, not appearance. If the same words sit in different positions, the text is identical — use Visual Compare to see layout differences.

What happens with scanned versions?

No text layer means nothing to compare, and the tool reports that. Use Visual Compare for scanned documents instead.

Does it detect a small change inside a long clause?

Yes. Comparison is word-level, so a single altered word in a 2,000-word clause is surfaced rather than buried.

Can this tell me who made the change?

No, it reports what differs. Check the PDF metadata on both files, which often identifies the author and the timestamp of each version.

Is either file modified?

No. Both documents are opened read-only for comparison.
