Edit DOCX in the Browser (Mostly Offline)

"Offline" and "browser editor" sound contradictory. Here is the honest split for EditDocx:

Needs network once

Loading editdocx.net the first time (HTML, JS, fonts). After that, document processing is local.

Local while editing

• Parse .docx in memory
• Auto-save to localStorage / IndexedDB
• Export DOCX or PDF bytes to download

0 server uploads for document content.

Not fully offline-first

If you close the tab before the app loads, or clear cache mid-session, you need network again. EditDocx is not a PWA with full offline install today.

FAQ

Can I edit on a plane after loading the page? Often yes for the current session — but do not rely on it for critical work without testing your browser cache behavior.
