About WAV and MP3
- WAV is uncompressed audio – exact quality, but about 10 MB per minute of stereo sound. Audio editors, DAWs and some upload forms ask for WAV.
- MP3 is the audio format every phone, car stereo, speaker, editor and website accepts. It's lossy, so files are small.
Tips for Android phone
- Converted audio shows up in music apps once it's in Downloads; to use an MP3 as a ringtone, pick it under Settings › Sound › Ringtone › add (+).
- No app from the Play Store needed, so there are no extra permissions, ads inside an app or storage used.
- The file is decoded by your browser's built-in audio support. If one browser can't open it, try Chrome or Firefox.

Frequently asked questions
Does converting WAV to MP3 reduce quality?
Slightly, as MP3 is lossy, but at 192 kbps it's very hard to hear any difference.
Can I cut the audio at the same time?
Yes. Drag the start and end handles on the waveform, preview it, and add a fade in or out if you want.
Is my audio uploaded to a server?
No. The conversion runs in your browser using your device's own processor, so your audio never leaves your device. You can even disconnect from the internet once the page has loaded.
Where does the converted file go on my Android phone?
Tap Download. The file lands in your Download folder – open it from Files by Google or Chrome's Downloads list.
