Preventing XSS Attacks with HTML Entity Encoding: Escaping Special Characters in Web Browsers

Admin Sep 24, 2026 296 reads

What is HTML Entity Encoding?

HTML entity encoding converts special characters that have reserved structural meanings in HTML (such as `<`, `>`, `&`, `"`, and `'`) into safe entity names or numeric codes (such as `<` and `>`). This prevents web browsers from interpreting user inputs as executable code.

Use our HTML Entity Encoder & Decoder Tool to escape strings safely.

Common HTML Entities

  • `<` (Less Than): Encoded as `<`
  • `>` (Greater Than): Encoded as `>`
  • `&` (Ampersand): Encoded as `&`
  • `"` (Double Quote): Encoded as `"`

How to Encode HTML Characters

  1. Open the HTML Entity Encoder tool.
  2. Paste your raw HTML string into the input area.
  3. Click "Encode Entities" to generate safe, escaped HTML code.
