Frequently Asked Questions
What characters need to be URL encoded?
Reserved characters like ?, &, =, /, #, and spaces must be encoded when used as data in URLs. The tool handles all reserved and unsafe characters according to RFC 3986.
What's the difference between full and component encoding?
Full encoding encodes the entire string. Component encoding (encodeURIComponent) is for encoding values in query parameters, preserving URL structure characters when needed.
Why are spaces sometimes + and sometimes %20?
In query strings (application/x-www-form-urlencoded), spaces can be represented as +. In other parts of URLs, %20 is used. The tool supports both conventions.
