About DOCX and HTML

DOCX content is read with Mammoth, which understands paragraphs, lists and tables.

HTML is rendered in a sandboxed document before printing to PDF.

DOCX files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • Word-specific features such as macros, comments and complex styles are not carried over.

Frequently asked questions

How do I convert a DOCX file to HTML?

Add your DOCX file to the box above. convertexa detects the format from the file content, applies the DOCX to HTML conversion and gives you the result to download. The whole operation runs inside your browser.

Are my DOCX files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the DOCX to HTML conversion lossless?

No. HTML is a re-encoded format, so some data is discarded to reach the target format. DOCX content is read with Mammoth, which understands paragraphs, lists and tables.

Is there a size limit?

For reliable results keep the input under 25 MB. Very large files run out of memory in the browser rather than failing quietly.

Which browsers are supported?

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
