Word Editor is a free and open-source text/document editor extension for your browser. It is very similar to popular word processor apps available in the market, except it works inside your browser without the need for any external plug-ins or software.

With Word Editor, you can open any text or HTML document and save the result in HTML format. While it currently does not support other famous document formats such as .doc or .docx, you can easily copy text from other software, like MS Word or webpages, and paste it into the add-on while preserving all the styles.

To ensure file I/O access, Word Editor utilizes the download API, meaning that all file storage operations occur in the default download folder of your browser. If you wish to change this folder, simply navigate to the extensions tab in your browser, search for download settings, and update the default folder to your preferred location.

Built on the popular TinyMCE JavaScript library, Word Editor provides a blank screen with a toolbar upon opening. You can then type or paste your document and save it as an HTML file in your system by clicking on the save button (File > Save).
