Frequently asked questions
Are my photos uploaded to a server?
No. Compression runs entirely inside your browser using its built-in image engine. Your photos never leave your device and are never stored.
Which format should I choose?
WebP usually gives the smallest files at the same visual quality and works in every modern browser. Choose JPEG for maximum compatibility, or PNG when you need lossless quality or transparency.
Is there a limit on file size or number of images?
No limits, no watermarks, no signup — processing happens on your own device, so serving you costs nothing and nothing is gated.
Where does 90% of the file size actually go?
JPEG throws away detail your eyes are bad at noticing — colour before brightness, fine texture before broad shapes. We explain the three tricks (chroma subsampling, the DCT and quantisation) with pictures: Where did 90% of my photo go?
