convert wav to mp3
Drop the WAV, leave MP3 selected and pick the bitrate. Each option shows the estimated size per minute, and the converted file appears in the queue with its size change against the original.
44 header bytes + 176,400 × 180.
16,000 bytes per second.
About 7.4 times smaller than the WAV.
The format maximum.
50% larger than the 16-bit one.
Input is whatever your browser can decode: MP3, WAV, OGG, OPUS, FLAC, M4A, AAC and WEBM audio, plus the audio track of MP4 and WEBM videos. Output is MP3, WAV, FLAC, OGG Opus and M4A (AAC). The last two depend on the browser's encoder, and the screen tells you when one is missing.
Yes, MP3 discards information and you cannot go back. At 192 kbps or higher most people do not notice a difference on ordinary music, but if you will still edit the audio, keep the WAV and convert only the final version.
Yes. The queue takes up to 40 files, converts one at a time and, with two or more done, offers a ZIP. They all use the same options, and if you change them afterwards a Convert again button appears.
No. The file is read, converted and packaged in the browser itself. The limit is 300 MB and 30 minutes per file, because the decoded audio has to fit in the memory of the device.
MP3 is written at a constant bitrate (CBR), the same across the whole file.
Conversion happens in your browser. No file is sent to a server.
