Change the format of your pictures in seconds. Convert PNG to JPG, JPG to WebP, WebP to PNG and more, one file or a hundred at a time. Transparent areas turn into a colour of your choice when saving as JPG.
Use JPG for photos, PNG when you need transparency or sharp graphics, and WebP for the smallest files on websites.
JPG can't be transparent, so transparent areas are filled with the background colour you pick (white by default). PNG and WebP keep transparency.
Only the first frame is converted.
