PPM is a simple uncompressed raster format from the Netpbm family, often used in image-processing pipelines.
PPM opens in GIMP, IrfanView and command-line imaging tools.
MP3 is the universal compressed audio format, balancing small size with good quality.
MP3 plays in every media player and browser.
No. Images and audio are fundamentally different, so there's nothing to convert. You can convert your PPM to PNG, JPG or TIFF instead.
Maybe a video or slideshow with audio — use a video tool. A PPM image can't hold sound.
PPM converts cleanly to PNG, JPG or TIFF — free, no sign-up, no watermark.
