About WaveNook

WaveNook makes simple, fast audio tools for everyone: checking a microphone before an interview, recording a voice note, making a ringtone or converting a file for an old car stereo. We build tools we'd want to use ourselves, which means no sign-ups, no watermarks and no uploading your private recordings to a stranger's server.

How our tools work

Every tool on WaveNook runs inside your web browser. When you open a file, your own device does the work using built-in browser technology and WebAssembly. Nothing is uploaded, so the tools are fast, work with large files, and keep your files private.

Free, without sign-ups

You'll never need an account or an email address. The site is paid for by ads, which we keep out of the way of the tools themselves.

Who we are

WaveNook is built and maintained by BlueEra. We'd love to hear which tool you'd like next, or about anything that doesn't work: get in touch.
