HTML entity encoder and decoder

Encode HTML-sensitive characters or decode entities without rendering unsafe markup.

How it works

Encode HTML-sensitive characters or decode entities without rendering unsafe markup. Review the displayed limits, choose your input, and run the operation. Browser tools keep data on this device. Server tools use private generated paths, isolated workers, verified outputs, and automatic deletion. Unsupported, malformed, or oversized inputs fail with a stable error without exposing their contents.
