How do you convert an image between PNG, JPG and WebP?
The image is drawn onto a canvas and re-encoded in the chosen format. JPG and WebP use the quality setting, while PNG is lossless; JPG has no transparency, so it is flattened on white. PNG suits graphics, JPG suits photos, and WebP usually gives the smallest file at similar quality. Everything runs locally in your browser.
