The package is released under the MIT license.

The bundled C# ThumbHash port is credited to Glitched Polygons GmbH, with Evan Wallace credited separately for the original algorithm and project. `THIRD-PARTY-NOTICES.md` records the full upstream MIT notice, the reviewed pull request, and the pinned source commit.

The package also uses [blurhash.net](https://github.com/MarkusPalcer/blurhash.net), [ImageSharp](https://github.com/SixLabors/ImageSharp), and the official JavaScript implementations of [BlurHash](https://github.com/woltapp/blurhash) and [ThumbHash](https://github.com/evanw/thumbhash). Each stays under its own upstream license.
