Report an error in a tool
Corrections are the most useful mail we receive, and they are always acted on. If a tool produced a wrong or surprising result, please include three things: the name of the tool or the page URL, the exact input you pasted, and the output you expected instead. Because everything runs in your browser, we cannot see your session or reproduce a failure from logs — that sample input is the only way to diagnose an inaccuracy. Mentioning your browser and operating system helps when the problem involves timezone handling or clipboard behaviour.
Request a tool or suggest an improvement
Suggestions for new utilities are welcome, particularly when you can describe the concrete task you were trying to finish. Requests that fit the site's constraints — runs fully client-side, implements a stable public standard, and solves one narrow problem — have the best chance of being built.
Privacy, advertising, and legal questions
For questions about the privacy policy, the advertising cookies described there, or anything on the terms and disclaimer pages, use the same address and mention which page you are asking about so the answer can be specific.
