Frequently Asked Questions

Expect a larger file: PNG stores every pixel of the photo without loss. Converting does not bring back detail already lost in the JPG.

A JPG has no transparency, so the PNG keeps the original background. To make the background transparent, use the background remover after converting.

No. The conversion runs entirely in your browser: your files never leave your device, which also makes it fast for several images at once.
