Why Images Save as WebP
Most big websites now deliver their images as WebP, because WebP files are smaller and pages load faster. When you right-click and choose "Save image as", your browser simply saves the file it received - a .webp.
That is great for page speed and frustrating when the file will not open in an older Photoshop, Word, PowerPoint or your favorite design tool. This converter turns it into a standard PNG that works everywhere, with the pixels carried over exactly.
