Questions

Is the output upper or lower case?

Lower case, which is the conventional form for hex dumps.

Is my text sent to a server?

No. This tool runs entirely in your browser — nothing you type or paste is uploaded, logged or stored anywhere.

Is there a limit on how much text I can use?

There is no fixed limit. Very large documents depend on your device’s memory, but ordinary pages and files are handled instantly.
