Encode and decode Blurhash values with this implementation written in Go.
About go-blurhash
go-blurhash is a pure Go library for BlurHash, a compact representation of an image placeholder used by Mastodon and other Fediverse software for preloading placeholders and hiding sensitive media. It generates a BlurHash string from an image, reconstructs a blurred image with specified dimensions from a hash, and can report the component counts stored in a hash.
The project notes it is presumably slower than the C reference implementation, uses additional memory to speed encoding, and recommends generating small images around 32x32px and scaling them up afterwards.
Key features
- Encode an image into a BlurHash string
- Decode a BlurHash string into a blurred image
- Specify width, height, and punch value when decoding
- Set x and y component counts when encoding
- Read x and y component counts from a hash
- Pure Go implementation for encoding and decoding
Best for: Go developers who need to generate or render BlurHash placeholders, including for Fediverse software.
Good for
- Pure Go implementation covering both encoding and decoding
- Provides encode, decode, and component-inspection functions
- Open source under GPL-3.0 license
Watch out for
- Presumably slower than the C implementation, with benchmarks pending
- Encoding increases memory usage to increase encoding speed
- Recommends generating small images and scaling up for performance

go-blurhash FAQ
How do I install go-blurhash?
From source with: go get -u github.com/buckket/go-blurhash
What functions does the library provide?
Encode for creating a hash, Decode for creating an image with chosen width, height and punch, and Components for reading x and y components from a hash.
How should decoded images be sized for performance?
Generate a very small image, around 32x32px, via BlurHash and scale it up to the desired dimensions afterwards.
