What is ThumbHash?
Get Started
ThumbHash is an alternative image placeholder algorithm. Placeholders are represented by small ∼28 bytes hashes. It's similar to BlurHash but with the following advantages:
- Encodes more detail in the same space
- Also encodes the aspect ratio
- Gives more accurate colors
- Supports images with alpha
This plugin adds ThumbHash support to Kirby, allowing you to implement UX improvements such as progressive image loading or content-aware spoiler images like Mastodon.
If you rather want to use BlurHash in your application, feel free to use my BlurHash plugin.
Under the hood, the heavy work gets done by a PHP implementation of ThumbHash by SRWieZ: SRWieZ/thumbhash
