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 HEIC? 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.
HEIC is the high-efficiency format iPhones and iPads use to store photos — about half the size of JPG, but not supported everywhere, so it often needs converting.
HEIC opens on Apple devices and Windows 11; older systems need it converted to JPG/PNG.
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→HEIC conversion.
M4A converts cleanly to MP3, WAV or AAC — free, no sign-up, no watermark.
