Convert MP2 to AAC — Free Online Converter

Converting MP2 to AAC upgrades broadcast audio from the MPEG-1/2 Layer 2 codec to its designated successor. AAC was explicitly designed by the MPEG committee to replace all three MPEG Audio Layers (MP1, MP2, MP3) with superior compression efficiency. The conversion moves audio from broadcast infrastructure to consumer distribution format.

MP2 at 192-256 kbps provides solid broadcast quality. AAC at 128 kbps matches or exceeds this quality in a format supported by every modern device, browser, and streaming platform. The conversion simultaneously improves compatibility and often reduces file size.

MP2 has excellent broadcast infrastructure support but poor consumer device support. Most smartphones, tablets, and web browsers do not include dedicated MP2 decoders. AAC is universally supported — converting MP2 to AAC makes broadcast content accessible to consumer audiences.

Streaming platforms and podcast directories require AAC or MP3 for submission. Converting MP2 radio or television audio to AAC is the standard step for republishing broadcast content as podcasts, streaming audio, or web media.
