MP3 to MP2
Convert MP3 audio to MP2 — right in your browser, nothing uploaded.
Drag & drop your MP3 files here, or click to choose. Everything runs in your browser — nothing is uploaded.
MP2 (MPEG-1 Audio Layer II) is an older lossy format still used in DAB digital radio and TV/broadcast chains. People convert MP3 to MP2 because broadcast and DAB radio equipment often expects an MPEG Layer II stream rather than MP3. This free MP3-to-MP2 converter does the whole job inside your browser using a WebAssembly build of FFmpeg, so your audio is never uploaded to any server and there is no size limit or queue. Drop in one file or a whole batch, choose a bitrate from 96 up to 320 kbps, and each file converts automatically — then preview every result in place and download it. No signup, no watermark, and nothing to install.
Frequently Asked Questions
How do I convert MP3 to MP2?
To convert MP3 to MP2, set the Bitrate dropdown first (96k, 128k, 192k recommended, 256k or 320k), then drag your MP3 files onto the drop area or click to choose them, and each converts to MP2 automatically in your browser. Set the bitrate before adding files, since it is read as each one converts. Every finished file gets a row with its new name, size, an inline preview player and a Download button, and nothing is uploaded.
Is this MP3 to MP2 converter free and private?
Yes on both counts: it is completely free with no signup, no watermark and nothing to install, and it is private because the whole conversion runs on a WebAssembly build of FFmpeg inside your own browser rather than on a server, so your files never leave your device. That makes it safe for private or unreleased recordings. The only download is the converter itself, a one-time roughly 32 MB file that is cached afterwards.
Will converting MP3 to MP2 lose quality?
Some quality is lost, because both MP3 and MP2 are lossy, so the audio is decoded and re-encoded and a little more data is discarded. Your MP3 is already lossy, so this cannot add quality back; it only repackages the sound already there. Choosing 192 kbps or higher, at or above your source's bitrate, keeps the difference very hard to hear.
Why convert MP3 to MP2?
People convert MP3 to MP2 because broadcast and DAB radio equipment often expects an MPEG Layer II stream rather than MP3. MP2 (MPEG-1 Audio Layer II) is an older lossy format still used in DAB digital radio and TV/broadcast chains. Converting re-packages your existing MP3 audio into MP2 so it drops straight into that workflow or device, without changing anything about how the original was recorded.
Which bitrate should I choose?
For most audio the default 192 kbps balances quality and file size well; pick 256 or 320 kbps to stay closest to the source, or 128 or 96 kbps for smaller files such as spoken word. Set the bitrate before adding files, as it is read when each one converts. Going above the source's own bitrate adds size, not quality.
Does it work on iPhone, Mac and Android?
Yes, it runs in any modern browser on Windows, Mac, Linux, iPhone and Android, with nothing to install and no account needed, so you can convert MP3 to MP2 on a laptop or straight from your phone. The first use downloads a one-time converter of about 32 MB, which your browser then caches so later conversions start instantly.
