About MP3
MP3 is the most widely supported audio format. Its lossy compression keeps files small while still sounding good, and it plays on essentially any device.
Questions
Is the MP3 converter free?
Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.
Which format should I convert my MP3 to?
It depends on what you need. For wide compatibility choose a mainstream format; for the smallest file choose a modern, efficient one. Each conversion page explains the trade-off.
