One Converter, Any Audio Format

This is the catch-all: if you're not sure which specific converter you need, upload here and get an MP3. For a particular format there's a dedicated page too — M4A, FLAC, OGG, WMA, AIFF, AMR. Converting to MP3 preserves the source; it can't improve it, so start from the best file you have and pick 320 kbps when quality matters.
