What is the HTML Entity Encoder/Decoder Tool?
HTML Entity Encoder/Decoder is a free web utility that converts characters like <, >, &, and quotes into safe HTML entities (such as < and &), or decodes existing entities back into plain text. Everything runs locally in your browser (html-entity-encoder) — nothing you paste in is ever sent to a server.
What Are HTML Entities and Why Encode Them?
HTML entities are special character sequences (like < for < or & for &) that let you safely display reserved HTML characters as literal text instead of having the browser interpret them as markup. This is essential when embedding user-generated text, code snippets, or special symbols into HTML pages without breaking the layout or introducing injection issues.
Key Features
- Two-Way Conversion: Switch between encoding plain text into entities and decoding entities back into readable text using the same input field.
- Fully Client-Side: Encoding and decoding both happen in your browser using native DOM APIs — no network request is ever made with your text.
- No Setup or Sign-up: Nothing to install or register for. It is instantly ready to use.
- Responsive Layout: Works cleanly on desktop, tablet, and mobile screens.
How to Use This Tool?
- Paste or type your text or HTML snippet into the input field.
- Click Encode Entities to convert special characters into HTML entities, or Decode Entities to convert entities back into plain text.
- The result appears instantly in the output box below.
- Select and copy the result to use it wherever you need.
Why Choose Our Client-Side Tool?
Most online encoder/decoder tools upload your input to a remote server to perform the conversion. That can expose source code fragments, internal markup, or other sensitive text to a third party. This tool runs the conversion directly in your browser, so your data never leaves your device.
