HTML Entity Encoder / Decoder
The ultimate tool to safely **Encode** your special characters (like `<`, `>`) into **HTML Entities** or **Decode** them back to original text.
Frequently Asked Questions
What is HTML Entity Encoding?
HTML entity encoding is the process of replacing special characters (like <, >, &, ") with their corresponding HTML codes (like <, >, &, "). This is essential to prevent browsers from misinterpreting these characters as actual HTML tags, especially when displaying code snippets or preventing cross-site scripting (XSS) attacks.
When should I use the HTML Entity Decoder?
The decoder converts HTML entity codes (e.g., & or ') back into their original, human-readable characters (e.g., & or '). This is useful for analyzing source code or restoring encoded text to its original format.
Is this tool safe for sensitive code?
Yes, this tool is client-side, meaning all encoding and decoding operations are performed directly in your web browser. Your input text is never sent to a server, ensuring your data remains private and secure.
What characters are typically encoded?
The most common characters that need encoding are: < (<), > (>), & (&), " ("), ' ('). These are essential for preventing HTML injection and XSS attacks in web applications.
Can I use this for XSS prevention?
Yes, HTML entity encoding is a fundamental technique for preventing Cross-Site Scripting (XSS) attacks. By encoding user input before displaying it on web pages, you ensure that any malicious scripts are rendered harmless as plain text.
