Feature flags
Checks texture-compression-bc, texture-compression-etc2, and texture-compression-astc through the browser WebGPU adapter.
WebGPU support checker
Check WebGPU compressed texture support in this browser
Run a local browser check for BC, ETC2, and ASTC WebGPU feature flags, then choose a texture output that matches your target runtime.
Tool entry
Browser support and web texture outputs
Use the detector first, then encode a texture with KTX2 or a Web preset that can transcode cleanly for the device.
WebGPU compression feature check
Query this browser's WebGPU adapter for compressed texture feature flags.
Run the check to see browser support.
BC compression
Common desktop GPU family for BC1, BC3, BC5, BC6H, and BC7 assets.
ETC2 compression
Common mobile and WebGL-oriented family for ETC2 texture targets.
ASTC compression
Modern mobile GPU family with flexible block sizes and high quality.
What this page covers
Output guidance
Connects support results to KTX2 and platform preset encoders instead of leaving you with a compatibility table.
Local workflow
The support check runs in your browser and texture conversion pages process files locally with WebAssembly.
How to use it
Run the browser feature check, review supported GPU compression families, and choose the matching texture conversion workflow.
- 01
Run the support check
Use the checker to query this browser's WebGPU adapter feature set.
- 02
Review BC, ETC2, and ASTC
Match the reported features to your target devices and rendering backend.
- 03
Encode a matching texture
Open the KTX2 encoder or Web preset converter and export a container for your runtime.
FAQ
No. It only asks the browser for the local WebGPU adapter and feature flags.
KTX2 is a practical delivery container because it can carry Basis Universal payloads and platform-ready compressed texture data.
Use KTX2 or Basis outputs that can still serve WebGL paths, and test the final asset in the actual target browser or engine.
