Extract text from project files (STPROJ)
To convert STPROJ projects to another format, you need Samsung Theme Editor or other Developer software.
To convert other file formats to the "Authoring Project Container" file type, you need software like Samsung Theme Editor or a similar tool.
The .STPROJ file extension represents a proprietary project container, most commonly a Samsung Theme Document used by Samsung Galaxy Themes Studio or an iAd Producer Project developed by Apple. These files store raw uncompiled assets like PNG images, XML configurations, and sound files used to build mobile phone UI themes or interactive iOS advertisements. The primary disadvantage of .STPROJ is its strict vendor lock-in. You must use specific, often discontinued, software to open or compile them. They require dedicated environments and cannot be viewed natively by web browsers or standard operating systems.
Users typically need to convert .STPROJ files to extract the underlying media, targeting formats like ZIP, JPG, or PNG. Because an .STPROJ is a complex package rather than a flat media file, standard online converters fail to process it. Only the original software can properly read or export the structured data into compiled distribution formats like APK. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your STPROJ 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 STPROJ converter.
