How to open an ODT file online

  1. Open your document. Drop an .odt, .ott or .fodt file onto the page, browse for it, paste it, or try the sample. Nothing is uploaded.
  2. Pick a view. Page view shows real pages with headers, footers and footnotes. Reading view reflows the text so you can make it bigger.
  3. Find what you need. Search with highlighted matches, jump through the outline, read the comments and check the document properties.
  4. Save or share. Save as PDF, export TXT, HTML or Markdown, copy all the text, or download the embedded images.

Shortcuts: Ctrl + F search, Enter / Shift + Enter next and previous match, Ctrl + P print, Ctrl + O open another file.

ODT viewer features

Export anything

Save as PDF, TXT, a self-contained HTML page or Markdown, copy all the text, or grab the embedded images.

Document properties

Title, author, dates, editing time, revisions, word and page statistics, plus the images and fonts inside.

100% private

Everything happens in your browser. The file is never uploaded and links inside it are never fetched.

Supported OpenDocument files

The viewer recognises the file by its contents, so a renamed file still opens in the right mode.

About ODT files

ODT (OpenDocument Text) is the standard document format of LibreOffice and Apache OpenOffice.

It is an open ISO standard, so governments, schools and companies use it to keep documents readable for decades.

Inside, an .odt file is a ZIP package with XML files for the text, the styles and the properties, plus a Pictures folder. You can look at those parts with the ZIP File Viewer and read the raw XML in the XML Viewer.

ODT vs DOCX

Both are ZIP-and-XML formats. ODT follows the OpenDocument standard, while DOCX follows Microsoft's Office Open XML.

Word opens ODT and LibreOffice opens DOCX, but complex formatting can shift on the way. To read a Word file as it was saved, use the DOCX Viewer.

Other document formats

Rich text files open in the RTF Viewer, e-books in the EPUB Viewer, and plain notes in the Text Viewer or Markdown Viewer. The full list is on the file viewers page.

Fonts that are not on your device are replaced with similar ones, so line breaks can differ slightly.

Yes. Save as PDF prints the pages exactly as shown, TXT gives the plain text, HTML gives one self-contained web page with the images inside, and Markdown keeps headings, lists and tables.
