Convert ODT to HTML

Convert a ODT document to a self-contained HTML page in seconds. The file is read directly in your browser, so nothing is uploaded and the result is ready almost instantly.

Your file never leaves your device.

How to convert ODT to HTML

This converter reads the structure of the ODT document, including headings, paragraphs, lists, tables and links, and writes it out as a self-contained HTML page. It is ideal for publishing on the web, email newsletters, CMS imports and quick previews in any browser. The engine runs locally with WebAssembly, which means large files convert quickly and privately without waiting for an upload.

Step 1: Choose your ODT file
Drag and drop a .odt file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Let it convert
The ODT is parsed on your device and turned into HTML automatically; there are no settings to worry about.
Step 3: Download the HTML
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

Headings are only recognised as headings when the original uses heading styles rather than bold, enlarged body text.
Password-protected files must be unlocked in the original application before converting.

Opens in every browser without Office, LibreOffice or a PDF reader.

Is it free?

Yes. Converting ODT to HTML is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Is my file uploaded?

The ODT file is processed entirely in your browser. It is never uploaded, never stored and never seen by anyone, so this is safe for confidential files.

About the formats

What is ODT?

ODT (OpenDocument Text) is an open standard for word processor documents and the native format of LibreOffice Writer and OpenOffice Writer. Because the specification is open, the format is supported by many applications beyond the two suites that created it. It is a popular, vendor-neutral alternative to proprietary word processor formats.

Use ODT when you work in LibreOffice, OpenOffice or another program that favours open standards, or when you want documents that are not locked to one vendor. ODT is also a safe interchange format between different office suites.

What is HTML?

HTML (HyperText Markup Language) is the markup language used to structure web pages, defining headings, paragraphs, links, images and more. Every website you visit is built on HTML. It is plain text that a browser interprets and renders into the page you see.

Use HTML whenever you publish content on the web, pages, articles, emails or anything meant to be read in a browser. It is also the destination format when converting a text document into a web page.

Frequently Asked Questions

Is ODT to HTML conversion free?

Yes. It is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Will the HTML keep the formatting of my ODT?

The structure is kept: headings, lists, tables, links and bold or italic text. Visual details such as fonts, colours, page margins and exact positioning are not part of HTML output, which uses a clean, readable default style.

What happens to images inside the ODT?

Images are not embedded in the output; the converter focuses on the text and its structure. If you need the images, export them from the original application.

Is it safe to convert odt to html here?

Yes. The work happens on your own device with WebAssembly and browser APIs, so the file is not uploaded at all. You can even disconnect from the internet once the page has loaded.

Do I need to install anything?

No. Everything runs in a modern browser (Chrome, Edge, Firefox or Safari) on Windows, macOS, Linux, Android and iOS. There is no app, plugin or account.
