Convert stereo to mono
Both channels are mixed into one, and you can lower the sample rate as well — 16 kHz is a common choice for speech. The file gets smaller, and the single channel plays the same in both ears.
Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.

Questions
- Will I lose anything by converting to mono?
- The difference between left and right disappears, because both channels are mixed together. For speech this rarely matters; music loses its sense of space.
- Which sample rate should I choose?
- 16 kHz is a common choice for speech and gives the smallest file; choose 44.1 or 48 kHz for music. Rates higher than the file's own are not offered — they would only make it bigger.
- How much smaller will the file be?
- The tool shows an estimate before you start. A mono WAV is half the size of a stereo WAV at the same sample rate, and a lower rate makes it smaller still.
