Converting formats can change image data. PNG is lossless, but converting a JPEG to PNG cannot restore detail already lost in the JPEG.

Images stay in this browser tab. The queue and generated previews/download links clear when you leave or refresh, and each item expires 30 minutes after upload or compression. Files you have already downloaded are saved on your device and cannot be removed by this page.
