or click to browse - works without LibreOffice installed
Drag and drop your .odt file onto the upload area, or click to browse. Works with documents created in LibreOffice, OpenOffice, and Google Docs - flat .fodt files are supported too. Up to 100 MB.
The document is converted locally using JavaScript - nothing is uploaded. Formatting is preserved, including headings, tables, lists, links, and embedded images, and a document outline built from the headings appears in the sidebar for one-click navigation.
Search the whole document with highlighted matches, jump to any page number, listen with read-aloud, bookmark positions, adjust font size and reading theme, print, and export the document as TXT or HTML - or extract every embedded image as a ZIP.
An automatic table of contents built from the document headings - click any heading to jump straight to that section.
Find any phrase with highlighted matches and prev/next navigation across the whole document.
Type a page number to jump there instantly, using the page count saved by LibreOffice in the document.
Built-in text-to-speech with selectable voice, speed, and pitch. Click any paragraph while listening to jump there.
The viewer remembers your position in each document, and manual bookmarks let you mark and revisit key sections.
Convert the document to plain text or a standalone web page - both generated locally in your browser.
Pull every embedded picture out of the document at original quality as a downloadable ZIP archive.
Sepia and night themes, adjustable font size, full screen mode, and print support - like a proper reading app.
All processing happens in your browser. Documents never leave your device - safe for contracts and official files.
ODT (OpenDocument Text) is the default document format of LibreOffice and OpenOffice, part of the OpenDocument Format (ODF) - an open ISO standard widely adopted by governments and organizations that require vendor-neutral file formats. Google Docs also exports .odt directly. A reliable ODT viewer lets you open these documents on any device with a browser, without installing an office suite.
Technically, an .odt file is a ZIP archive containing XML content, styles, metadata, and a Pictures folder with the embedded images - which is exactly what this viewer unpacks and converts locally in your browser. You can even browse the raw files inside an .odt with our Archive Viewer.
Both are ZIP-and-XML document formats, but ODT follows the open ODF standard while DOCX follows Microsoft's Office Open XML. Word can open ODT and LibreOffice can open DOCX, though complex formatting sometimes shifts in translation. For Word documents, use our DOCX Viewer - it offers the same reading features as this tool.
For fixed-layout documents use our PDF Viewer, for ebooks the EPUB Viewer, and for lightweight text the TXT Viewer and Markdown Viewer. The full collection is on the file viewers page.
Upload your .odt file here and read it directly in your browser - no LibreOffice, OpenOffice, or Word needed. The document renders with formatting preserved, including headings, tables, lists, links, and embedded images. It works on Windows, Mac, Linux, Chromebooks, and mobile.
Modern versions of Word can open .odt files, but formatting is sometimes altered in the conversion. If you just need to read the document, this viewer shows it instantly in your browser without any conversion or installation.

For pixel-perfect layout, export the file as PDF and use our PDF Viewer.
