Free Online Tools

Small, focused utilities that each do one thing well. No sign-up, no watermarks, no upload for most of them — the work happens in your browser.

Most tools run entirely on your device. Where that is true the card says so, and your files never leave your machine. The few that need real computing power say that instead.

Audio Tools

Loudness, format and repair utilities for musicians, podcasters and video editors.

AI Stem Separator Coming soon

Separate any song into individual stems. Runs on our GPU servers rather than in your browser, so this one needs an upload.

Why these tools exist

Most online audio utilities want an account, add a watermark, or upload your files to a server you know nothing about. These do not. 2 work today, and more are being built — each one added when it is actually finished rather than announced in advance.

They are made by Code of the Geeks B.V., an engineering company in the Netherlands. Ads on these pages pay for the hosting — that is the whole business model.
