HTML Encoder - Free Online IT Tool

📄 HTML Encoder

Convert sensitive characters to HTML entities to prevent XSS and ensure correct rendering.

ℹ️ About HTML Encoder

The HTML Encoder is a critical security and formatting tool. it replaces characters that have special meaning in HTML (like <, >, and &) with their corresponding 'HTML Entities'.

Security Benefits:

By encoding user-provided data before displaying it on a webpage, you prevent Cross-Site Scripting (XSS) attacks. If a user tries to inject a script like <script>, the encoder turns it into <script>, which the browser will display as text rather than executing as a script.

📖 How to use HTML Encoder

1. Enter the code or text you want to safely display in HTML.
2. Click 'Run Tool' to generate the escaped version.
3. The tool will convert symbols like '<' into '<'.
4. Copy the output and paste it into your HTML source code.

❓ Frequently Asked Questions

Which characters are escaped?

By default, the tool escapes ampersands (&), double quotes ("), single quotes ('), and the less-than (<) and greater-than (>) symbols.

Does this prevent all XSS?

HTML encoding is a major part of XSS prevention, but it should be used as part of a broader security strategy including input validation and Content Security Policies (CSP).
