About Compare Word

Compare Word files when a contract comes back from the other side without tracked changes, or when two people edited separate copies of the same report. Upload the original and the changed version and you get a redline report as a PDF: added text in green, deleted text in red and struck through, with both file names and a count of each at the top. With Also a Word file with tracked changes on, as it is by default, you also get a DOCX that holds every difference as a tracked change, as if the other side had edited with Track Changes on. Open it in Word and accept or reject each change on the Review tab. For two versions of a spreadsheet, Compare Excel marks every changed cell instead.

The comparison works on the words themselves, so it catches every edited clause, figure and list number. Chinese, Japanese and Korean text is compared character by character, and a paragraph added or removed as a whole shows as one change. Numbers are read as a whole, so a change from 18.6% to 19.2% shows as one edit rather than scattered digits. Formatting-only changes, like a word turned bold, aren't flagged, and headers, footers and footnotes are left out of the comparison. The PDF report and the tracked-changes file are both built from the text of the two files, so they show the words, not the page layout, and the tracked-changes file has no tables or pictures. The layout is only in your original files.

Why use Cubfile for this

  • Word-level redline

    Insertions appear in green and deletions in red with a line through them, shown within the full text so you see the context.

  • Changes to accept or reject

    The DOCX holds every insertion and deletion as a tracked change, ready for Accept and Reject on Word's Review tab.

  • Numbers read as numbers

    Amounts, dates and percentages count as one unit, so 1,200 changed to 1,250 reads as a single clear edit.

  • Works across formats

    Compare a DOCX with a DOC, RTF or ODT copy. The text is what counts, not the file type.

FAQ

Compare Word: questions and answers

Does Compare Word show formatting changes?
No. It compares the text, so changes to bold, fonts, colors or layout aren't reported. Every added, removed or rewritten word is, list numbers included. To compare the layout by eye, open both versions in the browser with Office Viewer.
Can I accept or reject the changes in Word?
Yes, and neither file needs tracked changes of its own. With Also a Word file with tracked changes on, you get a DOCX in which every difference is a tracked change, so you can go through them on Word's Review tab and accept or reject each one. It holds the text only, without tables, pictures or the original layout, so keep your original files for those.
Which file should I add first to compare Word documents?
The older version. The first file is treated as the original and the second as the changed one, so text that exists only in the second file shows up as added.
Can I compare two Word documents for free?
Yes. Comparing two files counts as one task. Visitors get 2 tasks in total and free accounts 2 a day, with files up to 50 MB each, while VIP has no daily limit and takes files up to 1 GB.
Are the documents I compare kept anywhere?
Only for an hour. Both files and the results are deleted automatically after that, and you can remove them earlier from the result page. Nobody here reads them.
