Questions, bug reports, and requests for tools that should exist are all welcome.
One person reads this, so a reply can take a few days. Plain email works better than a form, and it means there is no server here collecting your details.
Reporting a problem with a tool
Tell me which tool, which browser, and what you expected to happen. Do not attach the file itself — describe it instead, since the whole point of this site is that your files stay with you. Page count, file size, and where it came from are usually enough to reproduce the fault.
Suggesting a tool
The constraint is that it has to run entirely in the browser, with no server doing the work. That rules out a few obvious requests but it is what keeps every tool here free and private. If you have something in mind, say what you would use it for.
