Legal Tech's Missing DOCX Editor

Push the boundaries of your product's document experiences

Develop native DOCX editing for complex legal documents

After spending countless hours with high volumes of legal docs troubleshooting HTML-based WYSIWYG rich text editors, we decided to Open Source a best in class DOCX experience that integrates seamlessly with Word.

Exquisite formatting

Preserve DOCX formatting on import and export

SuperDoc doesn't alter the structure of the original document - we open the DOCX in your application- rather than converting to HTML then back again to deliver a closer to Word like experience on the web. This lets your users take advantage of advanced formatting and for you to turn their document complexity into a competitive advantage.
