Common use cases
Why it’s different
100% Private
Every model runs in your browser. Your files never leave your device — nothing is uploaded to a server.
True Alpha Channel
Exports preserve a real straight-alpha transparency channel (PNG / WebP / AVIF), not a baked-on background.
Free Forever
No account, no watermark, no credits. Open the tool and use it.
Works Offline
After the model downloads once it is cached, so the tool keeps working with no connection.
