Free ODT to HTML converter

Why convert ODT to HTML?

People convert ODT to HTML because ODT is LibreOffice’s format, and colleagues working in Word often cannot open it cleanly, while HTML can be published on the web or opened in any browser on any device.

How to convert ODT to HTML

1. Choose your ODT file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .html. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .odt file?

ODT is the open standard used by LibreOffice and OpenOffice Writer, and an ISO standard in its own right. It carries the same kinds of structure as DOCX — headings, lists, tables, pictures — and Word can open one, though formatting occasionally shifts.

What is a .html file?

HTML is the language of web pages: headings, paragraphs, lists, links, tables and images, marked up as structure rather than layout. Any browser on any device can open one, which makes it a convenient universal document format as well as a web one.

What to expect from this conversion

Headings, paragraphs, bold and italic text, lists, quotes, tables and embedded pictures are all carried across. Exact page layout, fonts and multi-column arrangements are not — and a scanned PDF holds no text at all, so there is nothing to extract without OCR.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your ODT file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about ODT to HTML

Is this ODT to HTML converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my ODT file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

What happens to the quality?

Headings, paragraphs, bold and italic text, lists, quotes, tables and embedded pictures are all carried across. Exact page layout, fonts and multi-column arrangements are not — and a scanned PDF holds no text at all, so there is nothing to extract without OCR.

Can I convert several ODT files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Can I convert ODT to HTML without Pandoc or LibreOffice or a script?

Yes — that is what this page is for. Pandoc or LibreOffice does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original ODT file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that ODT is LibreOffice’s format, and colleagues working in Word often cannot open it cleanly.
