Squoosh!
Squoosh is an image compression web app that reduces image sizes through numerous formats.
Privacy
Squoosh does not send your image to a server. All image compression processes locally.
However, Squoosh utilizes Google Analytics to collect the following:
Basic visitor data.
The before and after image size value.
If Squoosh PWA, the type of Squoosh installation.
If Squoosh PWA, the installation time and date.
Developing
To develop for Squoosh:
Clone the repository
To install node packages, run:
npm install
Then build the app by running:
npm run build
After building, start the development server by running:
npm run dev
Contributing
Squoosh is an open-source project that appreciates all community involvement. To contribute to the project, follow the contribute guide.

48 points · Open discussionIt's been a year since it was last posted, and since I learned about this handy tool just today I thought it would be good to share.
It's open-source, it's doing a great job at compressing images without noticeable difference with a simple interface and maintained by Google: https://github.com/GoogleChromeLabs/squoosh

Maybe a fork of https://squoosh.app/ ? The code for that is https://github.com/GoogleChromeLabs/squoosh

Did you check? There aren't really any sources there, either.
From having already spent some time looking into this to track down what, exactly, you should patch should you want to make modifications, it looks like it's using the decoder from the JPEG XL reference implementation, libjxl (which is available under a BSD license):
<https://github.com/libjxl/libjxl>
In Show HN: JXL.js – JPEG XL Decoder in JavaScript Using WebAssembly in Web WorkerTo answer my own question, they have extracted the decoder from this Google Chrome Labs "Sploosh" project [0], all the sources are here:
https://github.com/GoogleChromeLabs/squoosh/tree/dev/codecs/...
It's under an Apache license, and so the correct license applies.

In Show HN: JXL.js – JPEG XL Decoder in JavaScript Using WebAssembly in Web WorkerThe WASM is only 311kb, so for an image heavy site this can easily be offset by the savings on image sizes. It seems quite quick too, are there any benchmarks?
There isn't any source in the repository for the WASM, thats slightly worrying as it's difficult to confirm the Apache License realy applies. I assume you are using an existing JPEG XL decoding lib?
(Edit - Source here: https://github.com/GoogleChromeLabs/squoosh/tree/dev/codecs/...)
Are you doing any progressive decoding while it downloads? I believe that is one of the features of JPEG XL.
Anyone wanting a good overview of JPEG XL, there is a good one here: https://cloudinary.com/blog/how_jpeg_xl_compares_to_other_im...
Aside: This is a great example of how awesome Mutation Observers are, they are the foundation of so many nice new "minimal" front end tools like HTMX and Alpine.js

Disappointing. I'll have to figure out the JXL WASM polyfill. Maybe if I wait a few months someone else will do it for me?
There's https://github.com/GoogleChromeLabs/squoosh/tree/dev/codecs/... that provides `JXLModule.decode(data: BufferSource): ImageData | null`, but for a polyfill I suspect you'd want a method to get the dimensions of the image and an IntersectionObserver to defer actually decoding the image until it scrolls into view. Having to load the image with XHR is annoying.
