Extract text from Balsamiq wireframes (BMML)
To convert BMML wireframes to another format, you need Balsamiq Mockups or other Page Layout software.
To convert other file formats to the "UI Wireframe Mockup File" file type, you need software like Balsamiq Mockups or a similar tool.
The .BMML file extension primarily acts as a Balsamiq Mockups Markup Language File, which stores user interface wireframes and mockups created in early versions of Balsamiq Mockups. These files use a structured XML format to save the layout, text, and coordinates of graphical UI elements like buttons, menus, and text boxes. A secondary use for the .BMML extension is the Braille Music Markup Language File, an XML-based format developed by The Contrapunctus Project to digitally represent Braille music scores for visually impaired musicians.
Opening a .BMML file natively requires legacy versions of Balsamiq Mockups (Version 2 and older) or specialized Braille music readers. The modern Balsamiq suite has migrated to the BMPR (Balsamiq Project) format, which bundles multiple mockups and image assets into a single SQLite database. Because .BMML files are proprietary to specific older software ecosystems, they are notoriously difficult to share with clients, stakeholders, or developers who do not have the paid software installed.
Users typically need to convert .BMML files because the format is severely outdated, requires a paid desktop license to view properly, and is completely unsupported by standard web browsers. Sharing raw .BMML files often leads to broken layouts or missing image assets, as external images are only linked via local file paths rather than embedded directly into the file.
The best conversion targets for Balsamiq .BMML files are standard visual formats like PDF or PNG. Converting to PNG provides a flat, universally readable image of the wireframe, though all layered vector data will be lost. Converting to PDF allows for multi-page presentation and retains vector scalability for zooming. For Braille music files, converting to standard MusicXML or MID is necessary for cross-platform playback.
Because .BMML wireframes rely on proprietary Balsamiq rendering engines to translate XML coordinates into sketchy UI graphics, standard online converters often fail to process them accurately. Usually, only the original software can properly render or export the visual data. However, just drag and drop your file to identify the format on convert.guru. We can inspect the file and show the internal text content. Since our analysis detects the underlying XML structure, viewing raw data, extracting text notes, or rescuing lost file paths is still easily possible without a paid license.
Use Convert.Guru to open and convert your BMML file.
Users also converted BMPR, ZIP, LRF, CAF and AIF files.
If you want to convert BMML file to BMPR, INDD, QXP, PUB, PMD, PM6, PM7, PM8, PM9, PM10, PM11 or OMP, you can use Balsamiq Mockups or similar software from the "UI Wireframes and Mockups" category. In the File menu, look for Save As… or Export….
To convert MDI, PUB, PDP, PM4, P65, COMIC, WEBTEMPLATE, PMD, SPUB, INDD, PM5 or QXP files to BMML, try Balsamiq Mockups or another comparable tool in the "UI Wireframes and Mockups" category.
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.
