Frequently Asked Questions
What is HTML encoding?
HTML encoding replaces special characters (like <, >, &, ", ') with their corresponding HTML entity codes (e.g., <, >, &). This ensures the browser interprets them as text rather than HTML code, which is essential for security and displaying code snippets.
Why do I need to encode HTML?
Encoding is crucial for preventing Cross-Site Scripting (XSS) attacks when displaying user input on a webpage. It is also necessary when you want to display HTML code itself as text within a webpage without the browser executing it.
Does this tool handle non-ASCII characters?
Yes. By enabling the 'Convert Non-ASCII' option, the tool will convert characters like accented letters (é, ü), currency symbols (€, £), and emojis into their numeric HTML entity equivalents (e.g., ©). This ensures maximum compatibility across different encoding standards.
