Frequently asked questions

Which formats are supported?

Convert freely between JPG, PNG and WebP. Everything is re-encoded locally in your browser.

Does converting lose quality?

Only if you target a lossy format like JPG. PNG and WebP (lossless) preserve every pixel.

Are my photos uploaded?

No — pixels are read into memory and re-encoded on your CPU. Nothing is sent anywhere.
