Why encode HTML entities
Characters like <, >, and & have special meaning in HTML and must be escaped to display literally. This tool converts them to entities like < and &, or decodes entities back to readable text.
HTML Entity Encoder / Decoder
Switch between encode and decode to convert special characters to and from HTML entities.
How it works

How to use HTML Entity Encoder / Decoder
Use HTML Entity Encoder / Decoder to transform encodings in your browser. If you decode a JWT or similar token, that does not prove the signature is valid.
Tips for better results
Watch for padding and character-set issues. Never paste production secrets into a shared screen.
Privacy and offline-friendly processing
Whenever possible, HTML Entity Encoder / Decoder processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default.
