Different kinds of files
An image stores pixels; an audio file stores a sound waveform. Neither contains the other, so no tool can turn a sound recording into a picture.
Looking to turn a M4A into WEBP? Here's the honest answer — and the conversions that actually work.

M4A is an AAC-based audio format common on Apple devices and iTunes — better quality than MP3 at the same size.
M4A plays on Apple devices, iTunes and most modern players.
WEBP is a modern Google format using lossy and lossless compression to make images ~25–35% smaller than JPG or PNG at similar quality, with transparency and animation support.
WEBP opens in all modern browsers and recent Photoshop, GIMP and image viewers.
No. Audio and images are fundamentally different, so there's nothing to convert. You can convert your M4A to MP3, WAV or AAC instead.
Maybe a waveform/album-art image, or adding this audio to a video — those are separate tools, not a M4A→WEBP conversion.
M4A converts cleanly to MP3, WAV or AAC — free, no sign-up, no watermark.
