Generate HLSL output from GLSL source when a rendering stack needs DirectX-facing shader code.

When this conversion page is useful

Generate HLSL output from GLSL source when a rendering stack needs DirectX-facing shader code.

Useful for cross-platform engines that keep GLSL close to source but need HLSL for Windows targets.

The current GLSL -> HLSL route is labeled "Secondary" on this site, so it works best as an in-browser conversion and review step before target-side validation.

What to prepare before converting

Confirm that GLSL is the real source language and that the shader belongs to a vertex, fragment, or compute stage.

Start with a small, testable shader so semantics, entry points, and resource bindings are easier to verify after conversion.

If the output will be shipped, run the generated HLSL through the real downstream toolchain before treating it as final.

Common use cases
Move a shader snippet into a new graphics API or backend without rebuilding the workflow from scratch.
Inspect the same shader logic in a more familiar target language during debugging or code review.
Treat this page as a conversion workspace, then validate semantics inside the actual DirectX toolchain.
GLSL to HLSL FAQ

Is GLSL to HLSL ready for production use?

It is useful as an online conversion and review workspace, but production delivery should still include target-side compilation and validation for HLSL.

Which shader stages are supported on this page?

The main conversion routes currently focus on vertex, fragment, and compute shaders.

Why keep a dedicated GLSL source page as well?

The source-language page is better for batch upload and multi-target output, while this conversion page is tuned for a single search intent.
