is there a standard of proof these sites can provide about not sending data back to the servers? besides checking the network data, which it could delay to another visit or obfuscate easily

How exactly could it obfuscate it? You can see every request in its entirety and if you see a request that you can't read, that's already enough reason to not use it. As for delaying it, it would have to store it somewhere like localStorage, which is just as easily inspectable. If you're worried about that, loading it in a private window and switching to offline mode, then closing it after you're done makes any exfil…

A service worker could send it after the tab is closed.

Ahhhh the times we live in, when it specifically needs to be said that something like a image optimizer is privacy-aware. :( Anyway - looks nice and something I'll use from time to time, thanks!

Not just that, it is a "webapp". When did ImageMagick became old?

Most designers will end up use this

This looks promising. I would be interested to learn more about the experience you have had while building this service.

Yesterday, I released https://goart.netlify.app It's an experiment at using WASM-compiled Go code to create complex generative art drawings in the browser. Sounds cool, but I have had quite a few unexpected issues while building it. Especially, the part about having to use Web Workers to do the communication to and from the WASM instance.

I don't know, sorry. I mean, you can be completely sure that the website works offline by unplugging the cable/turning off your wifi connection after it's completely loaded. But that's just a functional test, not something you can expect users to do during a normal browsing session

thats not enough, it can send it in the next connection. unless you want to load a site once, and never connect your computer to the internet ever again.

its easy to hide from network inspection

If you're this concerned that the app might delay sending until later, I would probably suggest you just use ImageMagick or GraphicsMagick locally instead. I use it all the time for processing photos. If you want to clean exif data look at exiftool. It's in most repos.

yeah thats what i do, but i wanna be able to use services like this
