What the tool does, how to run it, and what to expect from the result.
A .jfif file is ordinary JPEG data with an extension some Windows PCs give saved images, which upload forms often reject. WebP is the compact web image format; pages load faster with it. Drop the file and download the WebP; other output formats are one click away. Nothing is uploaded.
