Category:Images which should be in PNG format

Wikimedia Commons has media related to Images which should be in PNG format.

These images were uploaded in a format such as GIF or JPEG. It is suggested that the original sources be revisited and that PNG files be uploaded in their places. For more information, see Wikipedia:Preparing images for upload. Images can be added to this category by placing the {{ShouldBePNG}} template on the image description page. Note: If the image is copyrighted, it should not be rendered any larger than is required for the purposes of identification and/or critical commentary. Remember, the policy is that JPEGs should only be replaced if they have bad artifacts, have lost transparency, or a PNG would have a smaller file size.
