About Music Tools

A metronome, instrument tuner, tone generator, BPM tapper and note-frequency chart — 100% in your browser using the Web Audio API, with no uploads, no signup and no microphone data ever leaving your device.

Privacy-first by design

Unlike most online tools that upload your files to a server, Music Tools does all the work right inside your browser with modern JavaScript and WebAssembly. That means your files are never sent anywhere — it's faster, works offline once loaded, and keeps your data completely private.

Free forever

All tools are free to use. The site is supported by unobtrusive advertising so we can keep building and maintaining useful utilities.
