How do you compare Word documents privately without Microsoft Word?
Compare Word documents privately in AlineaDoc: DOCX files are read in the browser and files are not uploaded to a third-party server.
Ready to try it? Open the in-browser document comparator (/app). You can start without an account. Files are not uploaded to a third-party server.
Private Word compare without the desktop app
Word’s own Compare command is excellent if you already live in Office and need an editable redline. If you do not have a license, or the other party sent a PDF, use PDF vs DOCX.
AlineaDoc is the review layer: decide whether the new DOCX is acceptable, with no third-party analysis upload.
Frequently asked questions
Is a private Word comparison the same as Word’s Review → Compare?
No. Word builds an editable redline. AlineaDoc builds a classified visual review in the browser. In-browser processing means not uploaded to a third-party server. Use Word when you must accept or reject changes inside DOCX; use AlineaDoc to decide first.
Do I need to register to compare DOCX files?
No. It is a free in-browser utility. Drop two Word files on /app without an account. There is no hard paywall on the local diff. Optional departmental plans add export if your team already likes the workflow.
Are .doc files supported?
The comparator reads modern DOCX. Save legacy .doc as DOCX in Word or LibreOffice first. That conversion stays on your machine; AlineaDoc then diffs the DOCX locally and files are not uploaded to a third-party server to a comparison server.
