What Is an OpenDocument Text File?
OpenDocument Text (.odt) is the word-processing part of the OpenDocument standard (ISO/IEC 26300), the format LibreOffice and OpenOffice Writer save by default. Google Docs, Word and Collabora can write it too, and many public bodies require it for documents they publish. The file is a ZIP package holding the text in content.xml, the styles and page layout in styles.xml and the pictures under Pictures/. The same document can also be saved as one flat XML file (.fodt), and OpenOffice.org 1.x wrote the older .sxw.
This viewer reads the document with its own code, in your browser: paragraph and character styles, headings with their outline numbers, numbered and bulleted lists, tables with merged cells, borders and fills, pictures, text boxes, page breaks, headers and footers. It then lays the document out with the same engine as the Word viewer and editor, at the document’s page size and margins.
The pages can be saved as a PDF, a Word .docx, PNG or JPG images, or a self-contained HTML page, and the document can be edited in the same editor as a .docx.
Who Uses OpenDocument Text Files?
LibreOffice and OpenOffice users at home, in schools and in offices that standardised on free software; governments and agencies that publish forms and reports in OpenDocument; and anyone who receives an .odt attachment on a computer, tablet or phone with no LibreOffice to open it.
Common Use Cases

- Turn an OpenDocument text document into a Word .docx or a PDF
- Edit an .odt document in the browser and save it as a .docx
- Save the pages as PNG or JPG images

Compatibility & Format Notes
Reads OpenDocument text documents (.odt), templates (.ott), flat XML documents (.fodt), master documents (.odm, with the text they hold) and OpenOffice.org 1.x documents and templates (.sxw, .stw). Carried over: text in any language, paragraph and character styles (font, size, bold, italic, underline, colour, highlight, alignment, indents, spacing and borders), headings with their outline numbers, numbered and bulleted lists with their indents, tables with column widths, merged cells, cell borders, fills and padding, pictures inline or beside the text, text boxes, page breaks, the page size and margins, and the header and footer of the first page style.
Footnotes and endnotes are listed after the text, at the end of the document, with their numbers kept in the text. Drawn shapes (lines, arrows, rectangles and callouts made with the drawing tools) and charts are not shown, and neither are comments or tracked changes. Lines can break in slightly different places than in Writer, because the text is set in metric-compatible open fonts.
A password-protected document shows a notice asking for an unprotected copy. OpenDocument presentations (.odp) and drawings (.odg) are recognised and named, with a notice suggesting a PDF export, and are not drawn. OpenDocument spreadsheets (.ods, .fods) open in the spreadsheet viewer.

Frequently Asked Questions
▶How do I open an .odt file without LibreOffice?
Drop it on this page. The viewer reads the file in your browser and shows it page by page, on Windows, macOS, Android, iPhone, a Chromebook or Linux. Nothing needs to be installed.
▶Can I convert an .odt document to Word?
Yes. Open it here and click Download: the document is saved as a .docx that Word, Google Docs and Pages open. Choose Download as PDF from the arrow beside it for a vector PDF.
▶Does it look the same as in LibreOffice?
Close. Text, styles, lists, tables, pictures, headers and footers are laid out at the document’s page size and margins, in open fonts with the same metrics, so lines can break a little differently. Footnotes are collected at the end of the document, and drawn shapes and charts are not shown.
▶Can I edit an .odt document here?
Yes. The document opens in the Word editor: type and delete text, change fonts, styles and lists, edit tables, add pictures and links, and download the result as a .docx or PDF. Saving back to .odt is not offered.
▶What about .odp presentations and .odg drawings?
They are recognised and named, with a notice, and are not drawn. Export them from LibreOffice Impress or Draw as a PDF and open that here. OpenDocument spreadsheets (.ods) open in the spreadsheet viewer.
▶Is this OpenDocument viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 100 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser: nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Download to save the document as a .docx, or choose Download as PDF from the arrow beside it. Export has the same PDF, the pages as PNG or JPG images, and the document as one self-contained HTML page.
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
