A "steganography-like" command-line utility consisting of two CLI tools, wbpin, used for embedding a data file within a WEBP cover image, and wbpout, used for extracting the hidden file from the cover image.
There is also a wbpdv Web App, which you can try here as a convenient alternative to downloading and compiling the CLI source code.
