Questions

How do I convert DOC to DOCX?

Drop your DOC file on this page, or choose it. Anyfile converts it on your device in a moment and the DOCX downloads straight away. To change it first, open it in the document editor.

Is my DOC file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several DOC files at once?

Yes. Drop them together and you get one ZIP with every DOCX inside.
