DOCX and DOC: what actually changes
DOCX is the Office Open XML word processing format — a zipped bundle of XML. DOC is the legacy binary Word format, superseded by DOCX in 2007.
The conversion runs through pandoc and LibreOffice, which parse the DOCX into a document tree and write it back out as DOC rather than doing anything textual or approximate. The DOC you get back keeps text, styles and embedded images, and gives up fidelity in anything but Word itself. Heavily designed, multi-column pages are where every converter struggles, so give those a look afterwards.
How it goes3 steps
-
Add your DOCX files
Drop them onto the box above or click Select File. Add as many .docx files as you like — the whole batch converts in one go, and duplicates are ignored.
-
Confirm DOC as the output
DOC is already selected as the target format on this page. Tweak the options if you need something other than a straight DOC file.
-
Download your DOC
Hit Convert and grab the finished DOC files individually or as a single ZIP. Everything is deleted from the server once you have them.
