MP3 file info

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

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.

Frequently asked questions

Can I tell if an MP3 was re-encoded from a worse source?

Not from the header alone; a high bitrate can wrap a poor source. The spectrogram tool reveals the telltale frequency cutoffs.

Is my MP3 uploaded?

No, inspection runs fully in your browser.
