Turn WAV, OGG, M4A, AAC, FLAC or the soundtrack of a video into an MP3, at a bitrate you choose. It all runs in your browser.
Quick answer: Pick your file, choose MP3 as the output and a bitrate — 192 kbps for music, 128 for speech — then download. Nothing is uploaded; the conversion happens on your device.

Bitrate is how many kilobits each second of audio is allowed to use. More bits means the encoder throws away less, and the file grows in direct proportion — a three-minute track at 320 kbps is two and a half times the size of the same track at 128.
The useful range is narrower than it looks. Most listeners cannot reliably separate 192 kbps from the original on normal equipment, and speech holds up at 128 or even below because the human voice occupies a narrow band. The place where low bitrates fall apart is dense music with cymbals and reverb, where the encoder runs out of room and the high end turns watery.
Extracting audio from a video
Converting an MP4, MOV, MKV or AVI to MP3 keeps the audio track and drops the video entirely, which is why a 200 MB clip becomes a few megabytes. It is the right tool for pulling a lecture, an interview or a piece of music out of a recording you already have.
If the file has no audio track at all, the converter says so rather than producing a silent MP3 — a genuinely empty result is more confusing than an error.
Frequently Asked Questions
WAV, OGG, M4A, AAC and FLAC, plus the audio track of a video file such as MP4, MOV, MKV or AVI. Converting a video to MP3 keeps only the sound and discards the picture, which is why the file gets so much smaller.
192 kbps is a sensible default for music and is hard to tell from the source in normal listening. 128 kbps is fine for speech, podcasts and voice notes and halves the size again. Going above 256 kbps rarely pays for itself, because MP3 discards the same information either way and you are mostly buying back file size.
Yes, unavoidably. FLAC is lossless and MP3 is not, so the conversion permanently discards detail the encoder judges inaudible. Keep the FLAC files if they are your only copy and treat the MP3s as the portable version.
Yes, and the site does it with two independent engines so one covers the other if it fails. Bear in mind that converting MP3 to WAV does not restore quality — it just stores the already-compressed audio without further compression, in a much larger file.
No. Conversion runs in your browser, so the file never leaves your device. That matters for voice memos, interviews and anything recorded privately.
No account limit. Long files use more of your device's memory since the work happens locally, so very large videos are limited by your machine rather than a plan.
