MP3 (MPEG-1 Audio Layer III) is the universal audio format, playable on every device and accepted by every audio app.
192 kbps is a good balance for music. 128 kbps is plenty for speech.
Frequently asked questions
Are my MP4 files uploaded?
No. The conversion runs in your browser, so your files never leave your device. You can even disconnect from the internet once the page has loaded.
Which bitrate should I choose?
Use 192 kbps for music and 128 kbps for speech. Higher bitrates make bigger files without a difference most people can hear.
