About

Chaos Lab Toolbox is a free collection of online tools, covering 17 categories and 140+ utilities for PDF, images, audio/video, text, calculations and development.

Our core principle is "files stay local": everything that can run in the browser is processed on your own device — better privacy, no sign-up and nothing to install.

The Site is independently maintained by an individual developer and supported by voluntary "buy me a coffee" donations to cover domain and server costs.

If you have suggestions or want a new tool, reach us via the contact page.
