Are my private photos uploaded to a server?

No! All compression takes place locally inside your browser memory using HTML5 Canvas and WebAssembly. Your files never leave your device.

How much file size reduction can I expect?

The amount of size reduction depends on the original codec, resolution, bitrate, format, and selected quality setting.
