WAV to MP3 — 320 kbps for the bounce that's leaving your DAW.
Drop a WAV master from Ableton, Logic, Reaper, FL Studio, Pro Tools or Audacity. We compress to MP3 at the bitrate you pick — clean LAME encode, full 44.1/48 kHz support, batch a whole album at once. Your unreleased mix never leaves your browser.

or click to pick. AIFF supported too.
What this is good for
- Converting an Ableton, Logic, or Reaper WAV bounce to MP3 320 kbps — Ableton Live 10+ exports MP3 directly, but Live 9, Reaper, and older Logic versions don't. Bounce to WAV, drop it here.
- SoundCloud / DistroKid / CD Baby / Bandcamp upload — most accept WAV but punish you on file size and upload time. 320 kbps MP3 sounds identical for streaming and uploads in seconds.
- Demo to a label, A&R, or collaborator — the WAV master stays on your drive, the MP3 goes in the email.
- Sharing a podcast WAV bounce — most hosting platforms re-encode anyway, so saving them the WAV upload time costs you nothing.
- Batch an album — drop the whole folder of stems or final masters, get a zip of MP3s back. Original filenames preserved.
- Convert AIFF too — Logic Pro's older AIFF bounces work the same way.
Which bitrate? Quick answer
- 320 kbps — for anything you're calling a "final" MP3. Streaming services, distribution, demos, the version you put in your portfolio.
- 256 kbps — old iTunes default. Indistinguishable from 320 to almost everyone.
- 192 kbps — good casual listening, ~40% smaller files. Reasonable for a working reference mix you send to bandmates.
- 128 kbps — only for voice, podcast roughcuts, or attachments where size matters more than fidelity.
How it works
Your browser decodes WAV/AIFF natively. We pipe the raw PCM samples into a JavaScript port of LAME (the reference open-source MP3 encoder) running in your tab. No upload, no codec install. Sample rate is preserved (44.1 or 48 kHz typical for music; we don't resample unless you ask).
FAQ
How do I export a 320 kbps MP3 from Reaper / FL Studio / older Logic?
Render or bounce to WAV first, then drop that WAV here and pick 320 kbps. None of those DAWs natively export 320 kbps MP3 without third-party plugins or paid versions.
Is 320 kbps MP3 good enough for SoundCloud / Spotify / DistroKid?
For SoundCloud, yes — they re-encode anyway, and they accept 320 kbps MP3 directly. For Spotify and Apple Music via DistroKid or CD Baby, the distributors actually want lossless (WAV or FLAC) for the final master. Use MP3 for everything that isn't a paid distribution upload.
Is 320 kbps the same as lossless?
No. MP3 is a lossy format at any bitrate. 320 kbps is the highest fixed-bitrate MP3 and the difference vs. lossless is inaudible to most listeners on most gear, but it isn't bit-perfect. For archival or remastering, keep the WAV.
Can I convert AIFF too?
Yes. Same tool, same workflow — Logic Pro's classic AIFF bounces work identically to WAV.
Does my master bounce get uploaded?
No. The encode runs in your browser tab. You can disconnect from the internet and it still works. Your unreleased mix stays on your drive.
Can I batch a whole album?
Yes. Drop all the WAVs at once and you'll get a zip of MP3s back with original filenames preserved.
How big can the WAV be?
Around 500 MB per file on a typical laptop. A 12-track album of 5-minute stereo WAVs at 44.1 kHz is well within budget.
