About DOCX and PDF

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

PDF output is generated directly, so pages stay sharp at any zoom level.

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

  • The document is rendered as an image-based PDF, so the text cannot be selected or searched afterwards.
  • Exact pagination can differ slightly from Microsoft Word because fonts are substituted.

Frequently asked questions

How do I convert a DOCX file to PDF?

Add your DOCX file to the box above. convertexa detects the format from the file content, applies the DOCX to PDF 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 PDF conversion lossless?

No. PDF 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 40 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.
