Common Use Cases
- Publishing OpenDocument content on the web
- Converting LibreOffice documents to web pages
- Creating HTML versions of formatted documents
OpenDocument Text is the native format for LibreOffice Writer, but publishing that content on the web means converting to HTML. This converter transforms your ODT into clean HTML with headings, lists, tables, and basic formatting mapped to semantic HTML elements.
ODT is a desktop document format stored as zipped XML, while HTML is the native language of the web. Converting maps document structure to semantic HTML elements browsers can render.
Why Convert ODT to HTML?
Publish documents on the web
Turn a LibreOffice document into a web page you can host, embed, or share via URL. No CMS required for simple publishing.
Preserve document structure
Headings, paragraphs, lists, and tables are mapped to proper HTML elements, maintaining the logical structure of your document.
Edit with any web tool
The resulting HTML can be edited in any code editor, CMS, or WYSIWYG editor. It integrates into any web workflow.
No LibreOffice required to view
Anyone with a browser can view HTML. No software installation needed, no compatibility issues, no download required.

Frequently asked questions
- Will formatting be preserved?
- Basic formatting like bold, italic, headings, lists, and tables is preserved. Complex page layout features like columns and text frames may be simplified.
- Are images included?
- Embedded images are typically exported alongside the HTML. The output may reference them as separate files or embed them inline depending on the document.
- Will the HTML be clean and semantic?
- LibreOffice produces functional HTML with inline styles. It is not hand-crafted markup, but it renders correctly in all browsers.
- Can I use this HTML in a CMS?
- Yes. You can copy the HTML body content into WordPress, Ghost, or any CMS that accepts HTML input.
- What about headers and footers?
- Headers and footers from the ODT may appear as regular content in the HTML, since HTML does not have a native page header/footer concept.
- Is there a file size limit?
- Yes. The maximum file size is 500 MB per file.
- Is this free?
- Yes. Free users get a daily conversion allowance. Registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
