We'd love to hear from you
Found a bug, have a tool idea, or a question about a result? Send us a message and we'll get back to you.
What to Write to Us About
- A result looks wrong - tell us the tool and what you entered (a domain, a number or a sample file name), so we can reproduce it.
- A tool you would like - describe the task you are trying to do; many of our tools started as a visitor's idea. You can also use the tools page to check whether it already exists.
- Something does not work on your phone or browser - mention the device and browser version.
- Privacy and data - most of our tools run entirely in your browser and never upload files; ask us if you want to know how a particular tool handles your data.
