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 MP3 into PGM? Here's the honest answer — and the conversions that actually work.

MP3 is the universal compressed audio format, balancing small size with good quality.
MP3 plays in every media player and browser.
PGM (Portable Graymap) is the Netpbm grayscale format, storing simple uncompressed gray images often used in image-processing research.
PGM opens in GIMP, IrfanView and Netpbm tools; convert to PNG/JPG to view widely.
No. Audio and images are fundamentally different, so there's nothing to convert. You can convert your MP3 to WAV, AAC or FLAC instead.
Maybe a waveform/album-art image, or adding this audio to a video — those are separate tools, not a MP3→PGM conversion.
MP3 converts cleanly to WAV, AAC or FLAC — free, no sign-up, no watermark.
