Frequently Asked Questions
What is HTML encoding?
HTML encoding converts special characters to their HTML entity equivalents. For example, < becomes <, > becomes >, and & becomes &. This prevents characters from being interpreted as HTML code.
When should I encode HTML?
Encode HTML when displaying user-generated content to prevent XSS attacks, when showing code examples on web pages, or when including special characters in HTML attributes.
Is HTML encoding the same as URL encoding?
No, they serve different purposes. HTML encoding is for displaying text in HTML documents. URL encoding (percent-encoding) is for including special characters in URLs. Use the appropriate encoding for each context.
Can I decode HTML entities back to text?
Yes, this tool can both encode and decode. Switch to decode mode to convert < back to <, & back to &, and other HTML entities back to their original characters.
