Need Your Document Online?

You created a document in LibreOffice or OpenOffice and now you need it on a website. ODT files are great for editing, but browsers cannot display them directly. HTML is the language of the web-every browser understands it.

Converting ODT files to HTML lets you publish your content online, embed it in emails, or integrate it into content management systems. The conversion preserves your text, headings, lists, and basic formatting so your document looks consistent on the web.

How to Convert ODT to HTML

  1. Upload your ODT file - Drag and drop or click to select your OpenDocument file
  2. Confirm HTML output - HTML is selected as your web-ready format
  3. Download your HTML - Your document is now ready for web publishing

The entire conversion happens in your browser. No account required, no software to install.

ODT vs HTML: Understanding the Difference

ODT (OpenDocument Text) is a word processing format used by LibreOffice, OpenOffice, and other office applications. It stores rich document formatting in a compressed XML structure.

HTML (HyperText Markup Language) is the standard markup language for web pages. Every website you visit is built with HTML. When you convert ODT to HTML, you are translating your document into a format that browsers can render natively.

In our testing, the conversion preserves paragraph structure, headings (H1-H6), bold and italic text, bullet lists, numbered lists, and hyperlinks. Complex elements like tables may require minor adjustments depending on their complexity.

When to Convert ODT to HTML

Website Content Publishing

You have documentation, articles, or guides written in LibreOffice. Convert to HTML and paste directly into your CMS, whether that is WordPress, Drupal, or a custom system.

Email Newsletters

Create your newsletter content in OpenOffice with proper formatting, then convert to HTML for email clients that render HTML content.

Online Documentation

Technical documentation written in ODT can be converted to HTML for hosting on documentation platforms or internal wikis.

Archiving for Web Access

Make old documents accessible online without requiring users to download files or have specific software installed.

What Gets Preserved

Our converter maintains the essential structure of your document:

  • Text formatting - Bold, italic, underline, strikethrough
  • Headings - Document hierarchy translates to HTML heading tags
  • Lists - Bullet points and numbered lists convert cleanly
  • Links - Hyperlinks remain functional in the output
  • Basic tables - Simple table structures convert well

Note that some advanced ODT features like macros, form controls, and complex page layouts may not have direct HTML equivalents. For print-focused output, consider ODT to PDF instead.

Alternative Formats to Consider

HTML is ideal for web publishing, but depending on your needs, other formats may work better:

  • ODT to PDF - Better for documents that need to look identical everywhere, especially for printing
  • ODT to DOCX - When you need to share with Microsoft Office users who need to edit the document

For content that will be viewed in browsers and needs to be searchable and accessible, HTML remains the best choice.

Works on Any Device

Convert ODT to HTML directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Tablets and mobile devices

No plugins, no downloads, no account creation. Your files stay on your device during processing.

Pro Tip

Before converting, use LibreOffice's built-in styles (Heading 1, Heading 2, etc.) rather than manual formatting. This creates cleaner HTML with proper semantic structure that is better for SEO and accessibility.

Common Mistake

Expecting pixel-perfect layout preservation. HTML is a flow-based format designed for different screen sizes. If exact layout matters, PDF is a better choice. HTML excels at flexible, accessible web content.

Best For

Publishing LibreOffice documents on websites, creating HTML email content, migrating documentation to web platforms, and making documents accessible online without requiring downloads.

Not Recommended

Documents requiring exact print layout preservation, files with complex multi-column designs, or documents with interactive form fields. Use PDF for print fidelity or DOCX for editable sharing with Office users.

Frequently Asked Questions

ODT (OpenDocument Text) is the default document format for LibreOffice Writer and Apache OpenOffice. It is an open standard format that stores text documents with formatting, images, and styles in a compressed XML structure.

Yes, essential formatting is preserved including headings, bold/italic text, lists, links, and basic tables. Advanced features like macros, form fields, and complex page layouts may not have direct HTML equivalents.

Basic images embedded in your ODT document can be included in the HTML output. For best results with image-heavy documents, consider whether a PDF format might better preserve the exact layout.

The conversion produces standard HTML that you can use directly on websites, in email templates, or as a starting point for further web development. The code uses semantic HTML elements for headings, paragraphs, and lists.

Absolutely. The HTML output is standard markup that can be edited in any text editor, HTML editor, or content management system. You can add styling, modify structure, or integrate it into larger web projects.

While LibreOffice can export to HTML, it often produces cluttered code with excessive inline styles. Online converters can provide cleaner output. Additionally, browser-based conversion works when you do not have LibreOffice installed.

Our converter handles typical document sizes efficiently. Very large documents with many embedded images may take longer to process. For extremely large files, consider splitting the document into sections.

Yes, batch conversion is supported. Upload multiple ODT files and convert them all to HTML in one session, which is helpful when migrating documentation or preparing multiple pages for a website.

Simple tables convert well to HTML table elements. Complex tables with merged cells or nested structures may require some manual adjustment after conversion to ensure they display correctly on all devices.

Yes. The conversion happens in your browser using client-side processing. Your document is not uploaded to external servers, so sensitive content remains on your device throughout the process.
