Found a bug, a file that fails, or a tool that behaves unexpectedly? We want to know — real failure reports are the fastest way these tools improve.

What helps in a bug report

which tool and what you did;
your browser and device (e.g. “Safari on iPhone”, “Chrome on Windows”);
the error message shown, if any;
rough size and page count of the file — please do not send the document itself if it is private; a description is usually enough.

There is deliberately no contact form and no newsletter — this page exists for support, not lead collection.
