What is the difference between Named, Decimal, and Hexadecimal entities?

Named entities use memorable aliases (like & or <), decimal entities use ASCII code numbers (like &), and hex entities use hexadecimal values (like &). All three are valid in HTML5.

Are my HTML documents or code snippets uploaded anywhere?

No. All escaping, sanitization, and entity translations occur strictly in your local browser sandbox with zero network telemetry.
