About BMML files

The .BMML extension primarily refers to the Balsamiq Mockups Markup Language, a legacy XML-based format used by Balsamiq Mockups 3 to store individual user interface wireframes. Unlike the modern BMPR format which bundles an entire project into a single SQLite database, .BMML files represent single pages.

Common Friction Points:
Users frequently encounter these files in archived project folders but cannot open them because Balsamiq Wireframes (the current version) and Balsamiq Cloud do not natively support editing single .BMML files without an import process. Furthermore, because it is a raw XML text file, attempting to open it in a browser or text editor displays code rather than the visual design.

Conversion Recommendations:

For Viewing & Sharing: Convert .BMML to PDF or PNG. This allows stakeholders to view the wireframe without installing legacy software.
For Editing: Convert .BMML to BMPR (Balsamiq Project). This is required to migrate old designs into modern Balsamiq versions.
For Braille Music: A minority of these files are Braille Music Markup Language scores. These should be converted to MusicXML for use in standard notation software like Sibelius or to PDF for visual verification.

The BMML Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BMML converter.
