WebODF: work with your office files in the cloud, on the desktop and on your mobile

WebODF used for editing

Editing a text document with the WebODF Editor.

WebODF is a JavaScript library that makes it easy to add Open Document Format (ODF) support to your website and to your mobile or desktop application. It uses HTML and CSS to display ODF documents.

Check out our demos and see what apps and other features are available.

WebODF is a Free Software project. All code is available under the AGPL. This means that you can use the code free of charge, investigate how it works, and share it with others. If you are interested in using WebODF in your commercial product (and do not want to disclose your sources / obey AGPL), contact KO GmbH for a commercial license.


WebODF 0.5.9 released, with important bugfix


This is a bugfix release that fixes an urgent issue. WebODF now makes absolutely sure that the mimetype file, which is used by many applications and some operating systems for identifying the mimetype of ODF files without having to depend on filename extensions or mimetypes, is not compressed within the ZIP container.

So go to the Download page and update your deployment of webodf.js or the Wodo.TextEditor. Or check the demos (general, features).

WebODF 0.5.8 released, with major bugfixes and optimizations


This release comes with a packaged Wodo.CollabTextEditor product, which is the Wodo editor component for collaborative text editing. It also introduces support for annotations in collaborative mode, removes some editing regressions introduced by changes in Browser APIs. Also of note is improved compression in generated documents (which should be much, much smaller now) thanks to JSZip, a javascript library for creating, reading, and editing ZIP files.

So go to the Download page and update your deployment of webodf.js or the Wodo.TextEditor. Or check the demos (general, features).
