Encode HTML Entities

Encode HTML entities so special characters can be stored or displayed safely.

Use this encoder/decoder when you need to encode HTML entities so special characters can be stored or displayed safely. It is useful for quick browser-based checks before you commit a snippet, send an API request, or write a one-off script.

For code and data tasks, start with a small representative sample before running a larger payload. Watch for encoding, escaping, indentation, delimiters, and hidden whitespace because those details often explain confusing output.

When the output feeds another development task, JSON validator, JSON formatter, and HTML formatter can help validate, format, inspect, or transform the result before it goes into code or an API.
