At the moment, all it can do is read all image formats that LibGfx can read and save to any image format that LibGfx can write (currently bmp, png, qoi). Currently, it drops all image metadata (including color profiles). Over time, this could learn tricks like keeping color profiles, converting an image to a different color profile, cropping out a part of an image, and so on.
