Extract text from ThemePark project files (TPARK)
To convert TPARK projects to another format, you need ThemePark or other System software.
To convert other file formats to the "Mac OS X Theme Project" file type, you need software like ThemePark or a similar tool.
The .tpark file is a proprietary ThemePark Project File originally created by the now-defunct ThemePark utility from GeekSpiff. It was actively used to build and store custom graphical user interface (GUI) themes for older versions of Mac OS X.
The major disadvantage of the .tpark format is its extreme obsolescence and closed-source nature. It is deeply tied to the legacy Apple Resource Fork architecture and deprecated PowerPC/early Intel APIs. You cannot open it on a modern macOS system, nor does it work on Windows or Linux. It requires the original discontinued software to properly read or export the data. Users often need to extract the custom icons, window skins, and UI elements trapped inside these files, but standard online converters fail because they lack the specific parsing logic for GeekSpiff's internal data structures. If our analysis detects a supported underlying or embedded format - such as embedded PNG, TIFF, or ICNS raster graphics - viewing or conversion may still be possible, rescuing your legacy graphical assets.
Convert.Guru analyzes your TPARK file, detects the exact format, and lets you read the text inside.

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 TPARK converter.
