There is no contact form here, because a form would need a server — and the whole point of this site is that it does not have one.
What to include
- Bug reports: which tool, which browser and version, and what the file looked like (format, rough size, dimensions). Please do not attach the file itself — describe it instead.
- Tool requests: tell us what you are trying to accomplish, not just the feature name. It usually reveals a simpler tool.
- Corrections: if something on a page is wrong, quote the sentence.
Response time
This is a small project. Expect a few days rather than a few hours.
