About this conversion
Upload a photo and open "Details → Background" to remove the background using an on-device AI model (a U²-Net-based network, running as WebAssembly directly in your browser). Download the result as a transparent PNG -- nothing about your photo is ever sent to a server.
Frequently asked questions
What kind of images work best?
Photos with a clear subject and reasonable contrast against the background -- portraits, products, and animals typically work well. Complex backgrounds or fine detail like hair can be less precise.
What format is the output?
A PNG with a transparent alpha channel where the background was removed, ready to drop onto a new background or use as-is.
Is this actually private, or does it just look local?
It’s genuinely local -- the AI model runs via ONNX Runtime Web (WebAssembly), loaded once and cached, with zero network requests for the actual image processing. You can verify this yourself in your browser’s network tab.
