Keep an image's format when downscaling it - #509
Merged
Conversation
Conditioning re-encoded every image as PNG. PNG is lossless, so a photograph comes out larger than the JPEG it came from despite having fewer pixels: ten photos totalling 7.6 MB became 30.6 MB, and the request carrying them was refused for exceeding the maximum size. A webp source is the one that cannot keep its format, because sips reads webp but cannot write it.
