What can we help with?
Report a bug
A tool isn't working correctly, produces wrong output, or crashes on certain files.
Tip: Include: which tool, file type, browser, and what you expected vs what happened.
Suggest a new tool
You need a tool we don't have yet. We genuinely build most suggestions.
Tip: Tell us: what the tool should do, what you'd use it for, and how often you need it.

Looking to partner, advertise, or commission a custom tool or web app.
Tip: Tell us about your project or partnership idea. We respond to all serious inquiries.
General feedback
Something you love, something we should improve, or a general comment.
