WAV to MP2
Convert WAV masters to broadcast-standard MP2, right in your browser, nothing uploaded.
Drag & drop your WAV files here, or click to choose. Everything runs in your browser — nothing is uploaded.
WAV is uncompressed PCM audio: perfect quality, but roughly 10 MB per minute of CD-quality stereo, which makes it heavy to store or hand off. MP2 (MPEG-1 Audio Layer II) is older than MP3 and is still what broadcast expects, from DAB digital radio to TV and professional playout chains, so a WAV master often has to become an MP2 before it can be delivered. This converter runs entirely inside your browser on a WebAssembly build of FFmpeg, so your recordings are never uploaded to any server. Drop in one file or a whole batch, choose a bitrate from 96 to 320 kbps (192 is the default), preview each result and download it. It's free, needs no signup, and installs nothing.
Frequently Asked Questions
How do I convert WAV to MP2?
To convert WAV to MP2, set the Bitrate dropdown above the drop area first (96k, 128k, 192k recommended, 256k, or 320k), then drag and drop your WAV files onto the drop area or click it to choose them; conversion to MP2 starts automatically and each finished file gets a Download button. You can add several WAV files at once, and they are converted one after another. Every row shows the new filename, its size, and an inline preview player, and the whole process runs in your browser through a WebAssembly build of FFmpeg, so nothing is uploaded.
Does converting WAV to MP2 lose quality?
Yes, a little. WAV is uncompressed PCM and MP2 is a lossy format, so the encoder permanently discards some audio data in order to shrink the file. A higher bitrate reduces the audible difference, and at 192 kbps or above it is hard to hear on most material. It is a one-way trip, though: converting the MP2 back to WAV will not bring the discarded detail back.
Which MP2 bitrate should I choose?
Use 192 kbps unless you have a reason not to; it is the default here and a safe middle ground for music and mixed material. Pick 256 or 320 kbps when the MP2 is a master or will be processed further downstream, and 96 or 128 kbps only for speech, where the smaller file matters more than fidelity. If a broadcast spec names a bitrate, use that.
Why would I use MP2 instead of MP3?
Because something in your chain asks for it. MP2 is older than MP3 but is still in active use in broadcast: DAB digital radio, TV and professional broadcast workflows commonly specify MPEG-1 Audio Layer II rather than Layer III. If you are delivering audio to a station, a playout system or an engineer who asked for Layer II, MP2 is the format they mean. For everyday listening, MP3 is the more universally compatible choice.
Is this WAV to MP2 converter free and private?
It is completely free with no signup, no account, no watermark and nothing to install, and it is private because the conversion happens on your own device. Your WAV files are never uploaded to any server; the WebAssembly copy of FFmpeg does all the encoding inside the browser tab. That makes it safe for unreleased music, interviews, and confidential or embargoed recordings.
Is there a file size limit for WAV files?
There is no limit imposed by this site, because nothing is uploaded and there is no server queue to wait in. The only real ceiling is your own device's memory, and WAV files get big fast at around 10 MB per minute of CD-quality stereo. Files past a few hundred megabytes can be slow or run out of memory on a phone, so use a desktop browser for long recordings.
Does it work on iPhone, Mac and Android?
Yes. The converter runs in any modern browser on Windows, Mac, Linux, iPhone and Android, since it is just a web page and there is no app to install. The first conversion downloads the roughly 32 MB converter engine, which your browser then caches so later conversions start instantly. Long WAV recordings are still better handled on a desktop browser, where there is more memory available.
