About this tool
Audio Convert swaps an audio file between WAV and MP3, right in your browser. Pick MP3 for a smaller file that's easy to share, or WAV for lossless, uncompressed quality. Nothing ever leaves your device.
MP3's bitrate setting trades file size for quality: 320 kbps keeps the most detail and is hardest to tell apart from the original, while 96 kbps produces a much smaller file at a more noticeable quality cost. There's no equivalent setting for WAV, since it stores audio uncompressed with nothing to trade off -- the file is simply larger.
Frequently asked questions
What bitrate should I choose for MP3?
320 kbps keeps the most detail and is the hardest to tell apart from the original, at the largest MP3 file size. 128 kbps is a reasonable middle ground for everyday listening, and 96 kbps trades more quality for a smaller file. Pick based on whether file size or fidelity matters more for your use.
Does converting to MP3 lose quality?
Yes -- MP3 is always a lossy format, even at its highest bitrate (320 kbps). It discards some audio detail during encoding to shrink the file. Convert to WAV instead if you need a lossless copy.
Does this change the sample rate or number of channels?
No -- the output keeps the original file's sample rate and channel count (mono or stereo) exactly as they were. Only the file format and, for MP3, the bitrate change.
Why is there no quality setting for WAV?
WAV stores audio uncompressed, so there's no bitrate to trade off the way there is with MP3 -- it always preserves full quality, just at a larger file size.
