  2. You’ll see a preview, if available.
  3. Click the "Convert file to..." button to extract text information.

Convert HLSL to another file type

To convert HLSL shaders to another format, you need Visual Studio or other Developer software.

Convert a file to HLSL

To convert other file formats to the "DirectX Shader Script" file type, you need software like Visual Studio or a similar tool.


About HLSL files

A .HLSL file contains 3D graphics rendering instructions written in the High-Level Shader Language developed by Microsoft. Game engines and graphics applications use these scripts to program vertex, pixel, and compute shaders directly on the GPU. Developers typically open and edit .HLSL files in text editors like Visual Studio or Visual Studio Code. To learn more, see the Wikipedia article on the High-Level Shading Language. The primary disadvantage of the .HLSL format is its strict dependency on the DirectX ecosystem. Casual users or developers on macOS and Linux cannot execute these files natively. Furthermore, raw .HLSL files are just uncompiled text-based source code. They cannot be executed directly; they must be compiled into machine-readable bytecode (such as CSO) using tools like the DirectX Shader Compiler before a graphics card can process them. If you need to read the code without a development environment, you should convert it to standard TXT. Developers porting games across platforms often need to convert .HLSL logic to GLSL (for OpenGL) or .SPIRV (for Vulkan). Because shader compilation and translation are highly specialized tasks, standard online converters often fail to process or translate shader logic.

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

The HLSL 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 HLSL converter.
