Convert a file to MASK

To convert other file formats to the "Transparency Map" file type, you need software like ImageMagick or a similar tool.


About MASK files

A .mask file typically represents a bitmap transparency map, most commonly generated by ImageMagick or the discontinued Adobe SpeedGrade. These files store grayscale data where black and white values define which parts of an image should be visible, opaque, or transparent.

The primary friction for users is that .mask is not a standard system extension; despite often containing simple raster data, operating systems like Windows and macOS do not know how to open them, and standard photo viewers will display an error. Furthermore, if the file originates from SpeedGrade, it is a legacy format from a tool that is no longer updated, creating a "proprietary lock-in" scenario where the original software is hard to access.

For most users, the practical solution is converting the file to a standard PNG (to preserve the transparency/grayscale nature), TIFF (for high-fidelity editing in Adobe Photoshop), or JPG (for quick reference).

Convert.Guru analyzes your MASK file, detects the exact format, and lets you read the text inside.

Users also converted JPG, PDF, BW, IMI, MIFF and IMAGE files.

The MASK 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 MASK converter.
