MP3 file info

Upload an MP3 file and inspect its technical details — codec, bitrate, sample rate, channels, and duration.

Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.

The full technical readout of an MP3

See the bitrate (and whether quality claims hold up), sample rate, channel mode, and exact duration of any MP3, parsed locally in seconds.

Typical checks

Verifying purchased downloads match their advertised bitrate, confirming a podcast export meets the host’s spec, and diagnosing files that report odd durations in players.
