What is MP2 to AAC Converter?
The MP2 to AAC Converter decodes MPEG-1 Audio Layer II files and re-encodes them as AAC. AAC is the standard codec for Apple devices, Android, and streaming platforms, offering efficient compression with modern device support. All conversion runs in your browser using FFmpeg via WebAssembly.
How does MP2 to AAC Converter work?
MP2 (MPEG-1 Audio Layer II) is the legacy broadcast audio codec used in DVB television and professional radio. AAC (Advanced Audio Coding) is the modern replacement for older MPEG audio standards, used by Apple Music, YouTube, and Android. This tool uses FFmpeg to decode MP2 and produce AAC output compatible across all modern platforms.

Pro Tips
- 1
AAC encoding requires a Chromium-based browser (Chrome, Edge, Brave). Firefox users should choose MP3 or OGG instead.
- 2
For editing, convert to WAV first before encoding to AAC.
- 3
This tool handles standalone .mp2 files. MP2 inside .ts containers must be extracted first.
- 4
AAC at 128 kbps is suitable for most broadcast audio content.
- 5
Keep your original MP2 files after conversion.
Frequently Asked Questions
Is AAC better than MP2?
At equal bitrates, AAC achieves significantly better audio quality. AAC also has far broader device support. MP2 is only maintained in broadcast infrastructure for legacy reasons.
Does converting MP2 to AAC lose quality?
Yes. Both are lossy formats. Transcoding applies a second round of compression and causes some quality loss.
Are my files uploaded to a server?
No. FFmpeg runs in your browser via WebAssembly. Files are processed locally.
Why does the first conversion take longer?
The first conversion loads the FFmpeg WebAssembly binary. This takes a few seconds. Subsequent conversions are immediate.
Why does AAC encoding require Chrome?
AAC encoding uses the WebCodecs API, which is only available in Chromium-based browsers. Use MP3 output if you are on Firefox.
