Good to know
WAV stores audio uncompressed. There is zero quality loss, which is why editors and studios use it, but it takes roughly 10 MB per minute.
MP3 is the most widely supported audio format. Its lossy compression removes sounds people barely hear, keeping files small, and it plays on virtually every phone, car stereo and speaker.
Converting WAV to MP3 shrinks it to roughly 1/7–1/10 of the size, making recordings and your own music easy to send by chat or email.
Conversion runs inside this browser and files are never sent over the internet. Because your phone or computer does the work, long videos may take a little while.
FAQ
Which bitrate should I choose?
128 kbps is enough for voice recordings; 192–256 kbps suits music. Choose 320 kbps for maximum quality.
Are my files uploaded?
No. Every conversion runs in your browser on your own device.
Does it work with long videos?
Yes, but it uses your device’s power, so a one-hour video may take a few minutes, and files over 2 GB may fail on phones.
