Found a bug, decoded something the tool got wrong, or want a format supported? We would like to hear about it.

When reporting a decoding problem

Please include your browser and version, the option settings you used, and — only if it contains nothing sensitive — a short sample of the input. Remember that we never see what you paste into the tool, so we cannot look it up on our side.

We read everything and reply to as much as we can, usually within a few working days.
