WAV to MP3
What to know before you convert
Bitrate cheat sheet
320 kbps CBR or V0 VBR is transparent for most listeners. V2 (~190 kbps) is the sweet spot for big libraries. 128 kbps is plenty for podcasts and voice memos.
Loudness too
Turn on normalize to bring quiet recordings up to a streaming-standard −14 LUFS, so they play at a consistent volume.
Frequently asked questions
CBR or VBR?
VBR (V0/V2) spends bits where the music needs them, so it's smaller at the same quality. CBR (e.g. 320 kbps) is the most compatible with old players and some upload sites.
How much smaller will the MP3 be?
About 4–5x smaller at 320 kbps and roughly 10x smaller at 128 kbps, compared with 16-bit / 44.1 kHz WAV.
Do my files get uploaded?
Usually not. Files up to 100 MB are converted on your own device with WebAssembly, so they never leave it. Larger files, or browsers that can't run the converter, use our servers; those files are deleted automatically after a short time.
What's the maximum file size?
Up to 500 MB per file and 20 files per batch by default. Files up to 100 MB are converted on your device.
