Convert DOCX to ZIP

Barely smaller, and that is expected. A DOCX already holds its contents in compressed form, so general-purpose compression has almost nothing left to find and the archive lands within a few per cent of the total it was given. Pack it anyway for the reasons that have nothing to do with size: one file to send instead of forty, one download, one checksum, and the folder layout preserved on the way out. A DOCX is a ZIP archive of XML parts — document body, styles, numbering, relationships — plus the media files it references.

For handling rather than for size. A DOCX is a ZIP container with a different extension and a required internal layout, so wrapping it in another one compresses essentially nothing — the second layer is there to bundle several files into one, to survive a mail system that mangles unusual extensions, or to stop a browser trying to open the file instead of downloading it. Unpacking gives back the original file untouched, not its insides.

Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.

Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.

Yes. Uploaded DOCX files are processed on our own servers and are never viewed or shared. Uploads and results are deleted automatically about 24 hours after conversion. See /privacy/ for the full policy.

Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download, you can re-trigger from the result page without re-uploading the DOCX.

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
