Get started

Three steps

  1. Download the installer for your OS from the latest release (Windows setup, macOS dmg, Linux AppImage or deb). Builds are not code-signed yet, so Windows SmartScreen or macOS Gatekeeper may warn.
  2. Drop a texture into the window (PNG, JPG, TGA and more), or use File › Open Image….
  3. Pick a preset or tweak the stack, compare with the split view, then export a PNG, TGA or BMP, full color or indexed.

Needs a GPU with WebGPU support. Windows 11 is the verified platform so far; macOS and Linux builds are produced by CI and feedback is welcome.
