How to convert SONG to MP3
If you have a song in a format like FLAC, WAV, OGG, M4A, or AIFF and want to play it on a device or platform that only supports MP3, converting to MP3 is the straightforward solution. MP3 is the most universally supported audio format with broad compatibility across every media player, smartphone, car stereo, and streaming device.

Frequently asked questions
What audio formats can I convert to MP3?
FLAC, WAV, OGG, M4A, AAC, AIFF, and WMA are among the supported input formats. Check the upload page for the current full list.
Does converting FLAC to MP3 reduce quality?
Yes. FLAC is lossless; MP3 is lossy. Converting from FLAC to MP3 encodes the audio with lossy compression. At 192 kbps or higher, the difference is generally not audible on typical speakers or headphones.
Are my audio files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Your files stay on your device throughout.
What bitrate is the output MP3?
The default output bitrate is shown on the tool. A higher bitrate produces better audio quality but a larger file size.
Why would I keep FLAC instead of converting everything to MP3?
FLAC is lossless and ideal for archiving music or for use in audio editing where re-encoding will occur. Use MP3 for portable playback where storage space matters more than perfect fidelity.
