Your files never leave your browser
Your files never touch our servers
Word Comparer runs entirely in your browser. There are no servers receiving your files — we literally cannot see what you compare. Close the tab and everything is gone.
Frequently asked questions
Are my Word documents uploaded to a server?+
No. Everything runs in your browser. Your files never leave your device and are never sent to any server.
What file formats are supported?+
Word Comparer supports .docx files. If you have a .doc file, save it as .docx first.
Can I compare more than two documents?+
The tool compares two documents at a time — an original and a revised version.
Does it show formatting changes?+
It focuses on text content changes — additions, deletions, and modifications — highlighted side by side.
Is there a file size limit?+
No strict limit — processing happens in your browser so performance depends on your device memory.
Is Word Comparer free?+
Yes, free for 5 uses per month with no signup. Upgrade to Pro for unlimited uses at €10/month.
