What is a .webp file?
A .webp file is a webP image. Its registered MIME type is image/webp, which places it in the image family of formats.
WEBP is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
Files of this type usually begin with the bytes 52 49 46 46. That signature is how programs recognise the format even when the extension is wrong or missing.
