Frequently asked questions
How much smaller will my image get?
It depends on the photo and settings, but JPEG and WebP compression often cut file size by 50–80% with little visible change. The savings are shown live.
Does compressing lose quality?
Lossy formats trade some detail for size, but at sensible quality levels the difference is hard to see. You control the trade-off with the quality slider or target size.
Are my images uploaded?
No. Compression runs entirely in your browser; your files stay on your device.
