Frequently Asked Questions

What does this HTML cleaner remove from Word documents?

It strips Word/MSO clutter — mso-* style properties, o:p tags, XML namespace blocks, conditional comments, empty tags, and class/id bloat — leaving clean, editor-ready HTML.

Is this tool free to use?

Yes, it's completely free with no sign-up required.

Does it upload my HTML to a server?

No. Everything runs 100% in your browser — your HTML is never uploaded or stored anywhere.

Can it merge duplicate span tags with the same style?

Yes. The "Merge same-style runs" option automatically combines adjacent spans (and bold/underline runs) that share identical formatting into a single tag.

Does it work on mobile devices?

Yes, the tool is fully responsive and works on phones and tablets.

What happens to images and links when cleaning?

By default, images and links are kept as-is. You can optionally remove images or convert links to plain text using the toggle options.
