Contact

Found a bug, spotted a mistake in a guide, or want a tool that isn't here yet? I'd like to hear about it.

Email: [email protected]

I read every message and usually reply within a few working days.

Reporting a bug

It helps a lot if you include:

• The page or tool you were using
• Your browser and device (for example, Safari on iPhone or Chrome on Windows)
• What you expected to happen and what happened instead
• A small example input, with any sensitive data removed

Suggesting a tool

Tell me what you'd use it for. Tools that solve a recurring, specific problem and can run entirely in the browser are the most likely to be added.
