Why a WebP file will not open
WebP is a modern image format. Many websites serve WebP because the files are smaller, so a picture saved from the web often arrives as a .webp file. Some older programs, office apps and upload forms still do not open it. Converting the file to PNG gives you a format that almost every editor, document and slide app accepts.
The picture itself does not change. The new PNG is a complete, separate file that you can keep next to the original. Keep the WebP for the web, where its smaller size helps, and use the PNG for everything else.
