Features
Real KTX2 to DDS conversion
Convert the top-level 2D KTX2 image directly to DDS without exporting PNG first.
BC7 by default
Keep BC1, BC3, and BC7 as target modes while defaulting to BC7 for higher quality DDS output.
Browser-side processing
Source decode, preview, and target encode all run locally in the browser.
Preview export stays separate
PNG remains the preview export format while DDS is downloaded as the actual target file.
Clear error boundaries
When DDS target formats require 4x4-aligned dimensions, the tool fails clearly instead of padding or resizing.
Built for DirectX workflows
Move KTX2 assets into DDS/BCn pipelines for desktop and game-engine validation.

No. V1 converts only the top-level 2D RGBA image and does not preserve mipmaps, array layers, cubemaps, or container metadata.
