What is URL encoding?

URL encoding (also called percent-encoding) converts special characters like spaces, ampersands, and non-ASCII characters into a format that can be safely transmitted in URLs. For example, a space becomes %20 and an ampersand becomes %26. This tool supports both encodeURIComponent (for values) and encodeURI (for full URLs).

What is the URL parser feature?

The URL parser takes any complete URL and breaks it into its individual components: protocol, hostname, port, pathname, query parameters (individually listed), hash fragment, and origin. This is useful for debugging API endpoints and understanding complex URLs.

What is Base64 URL encoding?

Base64 URL encoding is a URL-safe variant of standard Base64 that replaces + with -, / with _, and removes trailing = padding. It is commonly used for JWT tokens, API authentication, and safely embedding binary data in URLs. This tool handles both encoding and decoding.
