Frequently Asked Questions

Does it detect formatting differences like font size or bold changes?

Yes. Beyond text-level insertions and deletions, the tool can identify font family substitutions, font size adjustments, and full-width vs half-width character mismatches—changes that traditional track-changes comparison often overlooks.

Can I use this instead of Word’s built-in compare feature?

Yes, and in many ways it is more thorough. Microsoft Word’s compare focuses primarily on tracked changes and text edits. Our tool additionally compares structural formatting, detects seal/stamp differences, and works without any Microsoft software installed.

Need to verify a PDF version of a Word file?

If someone sent you a PDF export and you want to check it against the original Word document, use our PDF to Word Comparison tool. It cross-references the DOCX structure against the PDF text layer directly.

Does the comparison work with .doc (legacy Word) files or only .docx?

Both .doc and .docx formats are supported, along with WPS files. The AI converts legacy formats internally before comparison. For best formatting-level diff accuracy, .docx is recommended since it preserves more structural metadata.

Can I compare documents with tracked changes already enabled in Word?

Yes. The comparison is performed on the final document state. Existing tracked changes in either document are treated as accepted text. The tool then identifies the net differences between the two versions — giving you a clean, independent diff.
