What are HTML entities and why do I need to encode them?

HTML entities are special codes that represent characters in HTML. Characters like , &, and quotes need to be encoded to prevent them from being interpreted as HTML code. Encoding ensures your content displays correctly and protects against XSS (Cross-Site Scripting) attacks.

Is my text data safe when using this encoder/decoder?

Yes, absolutely! All encoding and decoding happens entirely in your browser using JavaScript. Your text never leaves your computer or gets sent to any server. This ensures complete privacy and security for any content you're processing.

What's the difference between encoding and decoding?

Encoding converts special characters to HTML entities (e.g., < becomes <). Decoding does the reverse, converting HTML entities back to their original characters. Use encoding when displaying user input in HTML, and decoding when you need to read entity-encoded content.

Which characters should I encode in HTML?

You should always encode , &, quotes (' and "), and any user-generated content displayed in HTML. This prevents HTML injection and ensures content displays as intended. Our tool handles all common HTML entities automatically.

Can this tool help prevent XSS attacks?

Yes! Encoding user input before displaying it in HTML is a crucial defense against XSS attacks. By converting special characters to HTML entities, you prevent malicious scripts from being executed. However, always use server-side validation as well.

Does this work offline?

Yes! Once you've loaded the page, the HTML entity encoder/decoder works completely offline. You can bookmark this page and encode/decode HTML entities anytime without an internet connection.
