Extract text from MYSTERY files
To convert your MYSTERY file to another format, you need IrfanView or other Raster Image software.
To convert other file formats to the "Renamed Graphic File" file type, you need software like IrfanView or a similar tool.
The .mystery file extension is typically a placeholder or obfuscated filename used to disguise standard file formats. Based on file signature analysis, approximately 62% of these files are actually Portable Network Graphics (.PNG) images, while around 12% are ELF (Executable and Linkable Format) binaries used by Unix-like operating systems.
Users often encounter this extension when extracting game assets, recovering data from cache folders, or dealing with developers who use non-standard naming conventions to prevent users from easily modifying assets. The main problem is that operating systems like Windows and macOS do not associate the .mystery extension with any default application, leaving the user unable to double-click and view the content. Furthermore, if the file is an ELF executable, attempting to open it as an image will fail, and vice versa.
For the majority of users holding image-based .mystery files, the best workflow is converting them to standard formats like JPG or WebP for broad compatibility with web browsers and photo viewers. If the file is an executable, it is generally not 'convertible' in the traditional sense but can be inspected or archived using ZIP or TAR.
Convert.Guru analyzes your MYSTERY 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 MYSTERY converter.
