An image editor that works offline
Because the tools run on your device, they keep working with no connection. Install ClearBG once and edit images offline — privately, with nothing uploaded.
ClearBG is a browser-based toolkit that does all of its work locally, so it doesn't need a live connection to function. Install it as an app (it's a PWA) and the interface is cached on your device — you can then compress, convert, resize, crop or redact images with the internet switched off entirely.
It's genuinely useful on a plane, on patchy hotel Wi-Fi, or any time you'd rather not send a photo over the network. Everything happens on-device, which is also why it stays private: no connection means there's nowhere for your images to go.
Why it stays private
Works with no connection
Once loaded, the tools run entirely on your device — no live server call to compress, convert, resize or crop.
Installable app
Add ClearBG to your home screen or desktop and it opens in its own window, cached for offline use.
Private, always
Offline by nature means private by nature — your images never leave the device they're on.
Tools that run on your device
All free, all private — nothing here uploads your images.

Why these tools keep working without a connection
A service worker holds the app
The first visit installs a small script that sits between the page and the network and keeps a copy of the site's own files — the HTML shell, the stylesheet, the scripts each tool needs.
On later visits it can answer from that cache. So a tool loads with no connection at all, which is why the site behaves like an installed application rather than a page you have to be online to reach.
The model is cached separately, and it is the big one
Background removal needs neural network weights, which are far larger than the rest of the site combined. They are fetched once and then stored, so the wait happens on the first cut-out and not again.
This is the one part that genuinely requires a connection the first time. Tools that need no model — cropping, converting, compressing, resizing — work offline from the first visit onward.
Offline as evidence rather than convenience
The useful property here is not that you can edit photos on a plane. It is that working offline is only possible if the processing was never remote, which makes it a demonstration rather than a claim.
Any tool that stops working when the network does was sending your file somewhere. That inference runs one way and needs no trust in anybody's documentation.
How updates reach a cached copy
Caching aggressively creates the opposite problem: a stale copy that never changes. The worker fetches from the network first for the site's own files when a connection exists, and falls back to the cache when it does not.
In practice a deployment is picked up the next time you load the site online, while an offline visit continues to work from what was stored. The model is treated the other way round — cache first, since a fixed set of weights has no reason to be re-checked.
