Convert your images between JPG, PNG, WebP, BMP and other supported formats.
Upload the PNG, choose JPG as the output format, then download. Remember that JPG has no transparency, so transparent areas become solid.
WebP usually produces a smaller file at similar quality and supports transparency. JPG is older and is accepted almost everywhere.
Converting to PNG keeps every pixel. Converting to JPG or WebP re-encodes the image, so some detail is lost each time you save.
Yes. WebP is accepted as input and can be converted to any of the supported output formats.
