Complete Guide: MP2 to AAC Converter
Everything you need to know about using this tool effectively
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.
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.
Upload broadcast recordings to streaming platforms
YouTube, Apple Music, and podcast hosts accept AAC but not MP2. Convert broadcast recordings to AAC before uploading.
Play DVB recordings on Apple devices
Convert MP2 audio from DVB television recordings to AAC for native playback on iPhone, iPad, and macOS.
Compact storage of broadcast audio
AAC achieves good quality at lower bitrates than MP2. Convert broadcast archives to AAC for efficient storage.
Deliver broadcast audio to mobile audiences
AAC is the preferred codec for mobile app audio. Convert MP2 broadcast clips to AAC for delivery to mobile users.
Modernise a broadcast audio archive
Convert a collection of legacy MP2 broadcast recordings to AAC for use in modern media workflows and distribution platforms.
Upload MP2 file
Click to browse or drag and drop your MP2 file into the upload area.
Wait for FFmpeg to load
On first use, the FFmpeg WebAssembly binary loads from a CDN. This takes a few seconds.
Convert
Click Convert to AAC. FFmpeg decodes the MP2 and the browser encodes the result as AAC.
Download AAC
Download your AAC file for playback on Apple devices, Android, or streaming platform upload.
AAC encoding requires a Chromium-based browser (Chrome, Edge, Brave). Firefox users should choose MP3 or OGG instead.
For editing, convert to WAV first before encoding to AAC.
This tool handles standalone .mp2 files. MP2 inside .ts containers must be extracted first.
AAC at 128 kbps is suitable for most broadcast audio content.
Keep your original MP2 files after conversion.
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.
