Open an ODT File Without LibreOffice

Someone sent you an .odt file and you do not have LibreOffice? Open it in your browser, edit it, and save it back as ODT — or as DOCX or PDF. Nothing to install, nothing uploaded.

How it works

1. Click Open your ODT to launch the editor in your browser.
2. Pick the .odt file from your device, or drag and drop it onto the page.
3. Read it, or edit it — it opens as a real document, not a preview.
4. Save it back as ODT, or export it as DOCX or PDF.

ODT is the OpenDocument Text format — what LibreOffice, OpenOffice and a lot of European public-sector systems produce by default. It is an open ISO standard, which is exactly why people choose it, and also why receiving one can be awkward if everyone around you is on Microsoft Word.

This editor opens ODT directly with the OnlyOffice engine compiled to WebAssembly, so paragraphs, styles, tables, images and lists render as a real document rather than a stripped-down text view. You can edit it and save it back as ODT, keeping it in the open format — or export to DOCX for a colleague on Word, or to PDF for someone who should only read it.

Nothing is uploaded: the file is read straight from disk into your browser tab. That matters for the kind of documents ODT tends to carry — government forms, academic drafts, anything from an organisation that picked an open format on purpose and would rather not route it through a commercial cloud.
