Does the platform preset converter upload my images?

No. Source loading, preview, and texture encoding run locally in your browser with WebAssembly.

Which outputs do the presets cover?

The page includes Web KTX2, Android/iOS ASTC, desktop DDS BC7/BC1, and HDR BC6H output presets.

Platform Preset Converter

Upload a source image, pick a target platform preset, and apply the recommended container, compression format, quality, and mipmap settings.

Upload source image

Drag and drop PNG, JPG, TGA, TIFF, HDR, or EXR here

Choose source image

HDR input note

HDR, EXR, and UltraHDR JPEG files can be used as inputs. Most current output paths still tone map into the RGBA8 encode pipeline; use DDS BC6H, KTX2 RGBA16F, or KTX2 RGBA32F when you need to preserve HDR source data as much as possible.
