Question 1

What is URL encoding?

Accepted Answer

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).

Question 2

What is the URL parser feature?

Accepted Answer

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.

Question 3

What is Base64 URL encoding?

Accepted Answer

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.
