About OSL files

The .OSL file extension primarily represents an Open Shading Language shader file. Created by Sony Pictures Imageworks and now managed by the Academy Software Foundation, OSL is an advanced shading language used to define materials, lights, and displacement in 3D rendering engines like Blender, Autodesk 3ds Max, and Arnold. These files contain human-readable source code describing how light interacts with surfaces. A secondary use for .OSL is a serialized object data file generated by the Microsoft .NET Framework using the BinaryFormatter class. Managing .OSL files can be highly frustrating depending on the context. OSL shader files often require compilation into .OSO (Open Shading Object) byte-code formats before a rendering engine can execute them efficiently, and sharing uncompiled .OSL files often results in missing dependencies or compatibility issues between different renderers. Meanwhile, .NET serialized .OSL files are binary, entirely unreadable in standard text editors, and pose severe security risks because the BinaryFormatter is deprecated due to critical deserialization vulnerabilities. To resolve these issues, conversion is necessary. For shading workflows, convert .OSL to .OSO for direct engine use, or export the code to plain TXT or CPP for collaborative review and archiving. For .NET objects, extracting data to XML or JSON makes it safely readable without triggering dangerous deserialization routines.

The OSL 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 OSL converter.
