Stored data
The processing happens inside your tab, so the models have to live there too. They download once and stay in the browser cache — otherwise every background removal would start with megabytes of downloading.
What is taking up space
Checking what is stored…
No images here, and there never will be
The files you process are not stored anywhere: not on a server, not in the browser cache. They live in the tab’s memory while it is open and disappear with it.
Working without a network
The site shell is stored by a service worker, and the codecs are stored the first time they are used. After that, converting and resizing work offline. Background removal and upscaling need a model: if it is already cached, those work too.
