What this tool does
Many images saved from websites arrive as .webp, and plenty of software still refuses them: older versions of Office and Photoshop, some printers, upload forms and messaging apps. PNG opens everywhere and, unlike JPEG, keeps transparent backgrounds. Because PNG is lossless the file will usually be bigger than the WebP, sometimes several times bigger, but it will not lose any more quality. If the picture is a photo and size matters more than transparency, the WebP to JPG converter gives a smaller file.
Formula
difference = (size before − size after) ÷ size before
