Nothing is uploaded
Audio is processed by a WebAssembly build of ffmpeg inside your browser, so meeting recordings, interviews and confidential voice-overs never touch the network.
No sign-up, no install
Open the page and start working. No account, no app, no usage cap, no watermark, and no cost.
Works on a phone
Everything runs in mobile browsers on iOS and Android. You can build and install an Android ringtone without ever touching a computer.
Frequently asked questions
Are my audio files uploaded?
No. Every operation runs as WebAssembly in your browser. Once the engine has loaded the page keeps working offline, so file contents never leave your device.
Is it free? Do I need an account?
Every tool is free with no sign-up and no install. There is no cap on files or runs — the only ceiling is your browser memory.
How do I make an iPhone ringtone?
Use the iPhone ringtone maker. It cuts up to 40 seconds and writes the .m4r format iOS requires, and the page explains how to get the file onto the phone.
Which formats are supported?
MP3, M4A, WAV, OGG, FLAC, AAC, Opus and WMA, plus audio extraction from video containers such as MP4, MOV, WebM and MKV.
