Frequently Asked Questions

What is URL encoding?

URL encoding (percent-encoding) converts special characters to %XX format for safe transmission in URLs. For example, space becomes %20, & becomes %26.

What are HTML entities?

HTML entities represent special characters in HTML. For example, < becomes <, > becomes >, & becomes &. This prevents XSS attacks and display issues.

When should I URL encode?

URL encode when: passing data in query strings, creating links with special characters, or working with APIs. Characters like &, =, ?, and spaces must be encoded.

What's the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL (preserves :, /, ?, #). encodeURIComponent encodes everything, used for query parameter values. This tool supports both.

Why do I need to encode HTML?

HTML encoding prevents XSS (Cross-Site Scripting) attacks by converting < > & " to entities. User input displayed in HTML should always be encoded.
