Are my images uploaded to a server?
No. Compression happens entirely in your browser; files never leave your device.
Which formats are supported?

How much quality is lost?
You control it with the quality slider. Around 80% is usually visually identical while cutting size significantly.
How many images can I process at once?
There is no hard limit, but very large batches use more memory — tens of images is recommended.
