Frequently Asked Questions
What does HTML encoding do?
HTML encoding converts special characters like <, >, &, and quotes into their corresponding HTML entities so they display correctly in HTML documents without being interpreted as markup.
When should I use HTML encoding?
Use HTML encoding when you want to display code snippets on a web page, prevent XSS attacks, or safely include user-generated content in HTML without breaking the page layout.
What is the difference between encode and decode?
Encoding converts special characters to HTML entities (e.g., < becomes <). Decoding does the reverse, converting entities back to their original characters.
