Questions
- How much smaller will the MP3 be?
- A minute of stereo WAV at 44.1 kHz takes about 10 MB; the same minute as a 128 kb/s MP3 takes about 1 MB. A mono WAV shrinks less — about five times.
- Which WAV files does it read?
- Ordinary uncompressed WAV — 16, 24 and 32-bit, mono or stereo — and telephone μ-law WAV. Rare compressed variants, such as ADPCM from some dictaphones, this browser may not read; the tool tells you so before converting.
- Will I lose quality?
- MP3 is a compressed format, so it removes the detail the ear notices least. For speech, 128 kb/s is plenty; if you plan to edit the recording further, keep the original WAV too.
- Are my files uploaded anywhere?
- Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
