free · in-browser · no upload
Drop your HTML file. We'll convert it to DOCX right here in your browser, your file never leaves your device.
Select your file here to get started
or drop your file here.
Accepts .html, .htm
How it works
Click the dropzone above or drag a HTML from your desktop. Files of any size, there's no upload, so there's no upload limit.
The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.
Get your DOCX the moment the conversion finishes. Convert another, or close the tab.
Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.
Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.
No account required. No watermark on the output. No queue. Drop a file, get a converted file.
Formats involved
HTML is the markup language of the web, every browser displays HTML documents natively. Files contain text plus tags (<h1>, <p>, <a>, etc.) describing structure and links. Modern HTML5 also supports embedded media (audio/video) and complex semantic markup.
How to open
Every web browser. Any text editor for source. Modern editors (VS Code) syntax-highlight HTML.
DOCX is the file format Microsoft Word has used since 2007, a zip containing XML, images, and styles. It replaced the older binary .doc format and is now the de facto standard for editable documents. Google Docs, Apple Pages, and LibreOffice all read and write DOCX, though formatting fidelity varies for complex layouts (tables, embedded objects, custom styles).
How to open
Microsoft Word (paid), Google Docs (free, web), Apple Pages (free, macOS/iOS), LibreOffice (free, all platforms), or any modern web-based editor like OnlyOffice.

FAQ
Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.
Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.
Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.
Web pages; structured document interchange; readable archives. Editable text documents; the de facto office document standard. The most common reason to convert is compatibility, DOCX works in places where HTML doesn't, or vice versa.
Every web browser. Any text editor for source. Modern editors (VS Code) syntax-highlight HTML.
Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.
Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
