It’s JavaScript.
And it is slow, but not as slow as I expected it to be. I’ve optimized a photo I’ve taken with my DSLR, 6.3MB, 24MP, JPEG. It has taken ~50sec on this phone, in Firefox.
I know, it’s a phone, but also, my phone can and does save, optimize, and apply filters to such images in <1sec.

If you are interested (and can pull together a bit of funding) I can look into how we could do this optimization in WASM.

Yes, it’s all JavaScript and essentially relies on the Canvas API to compress the images, so the performance is heavily dependent of your device and browser. I haven’t delved into WASM yet, but it would indeed open up doors for improvements, such a more file format support and more intelligent optimization. At the moment, working with canvas keeps things a lot more straightforward, however.
There is no funding I can provide at all (I’ve received 2 donations so far, which I’m very grateful for!). I just do this on my spare time, which I have a lot less of these days. I initially created MAZANOKE as a drop-in replacement for family and friends, specifically to those who tend to use questionable or ad-bloated online tools.

I did also forget to say it does look very nice, with animations and proper polish!

If you do delve into improving the performance, I suggest using Rust and
no_stdcrates for dealing with images, such as docs.rs/zune-jpeg/latest/zune_jpeg/.It would probably take some time to get it working, but it would probably increase performance and support any format you can find a crate for. But it does not seem like it’s worth it.
I’ll add this to my list of “things I might to when I don’t have a side project to waste my time on” :D

Thanks for your kind words, I tried putting some effort into making the interface a bit more fun and interactive, so thanks for noticing!
In regards to Rust, I’ve been interested in learning more about it, but I’ve not had time yet, so it’s been in a “soon ™” limbo. As I’m comfortable with JavaScript/JS frameworks, sticking with JS was a quick way to get started without much friction.
