While Word has Track Changes, converting both documents to PDF and comparing visually catches layout differences, spacing changes, and font shifts that Track Changes misses.
In Microsoft Word, File → Save As → PDF for each document. Or use pdfeditor.onl/convert-pdf (DOCX → PDF) for both.
Go to pdfeditor.onl/compare-pdf. Upload the first DOCX-as-PDF as File A and the second as File B. Click Compare.
Tip: PDF comparison shows visual differences including layout shifts, font changes, and spacing adjustments that Word's Track Changes does not detect.
Switch to Diff view. Every changed pixel is highlighted in red — showing exactly where the documents differ, including subtle formatting changes.
PDF comparison is better for: catching layout/formatting differences, comparing documents from different sources (one from Word, one from Google Docs), and when Track Changes history was not maintained.
Yes — both the converter and compare tool are completely free.
