DOCX

Office Open XML Document

DOCX is a ZIP of XML parts describing a Word document’s content and styling separately. It is an editable format, which is what makes converting a fixed-layout PDF into one so unreliable.

Extension: .docx
MIME type: application/vnd.openxmlformats-officedocument.wordprocessingml.document
Also called: Word

01 Convert DOCX to something else

Opening a .docx file

If you landed here because something handed you a .docx file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
