Encode and decode URL components correctly
URLs reserve characters such as spaces, ampersands, question marks, slashes, and hash signs for structural purposes. Encoding converts unsafe characters into percent-encoded sequences so a search term, query value, redirect target, or tracking parameter can travel inside a URL without being misread. Paste the text or component, choose Encode or Decode, and copy the result into the appropriate part of your link.
Encode individual parameter values rather than repeatedly encoding an entire URL. Double encoding turns a percent sign into %25 and can produce links that look valid but fail when opened. Decoding is useful for inspecting tracking links and debugging requests, but it does not prove that a destination is trustworthy. Treat unfamiliar decoded URLs as untrusted, and never place passwords, private tokens, or personal information in query strings because URLs may be stored in browser history, logs, and analytics systems.
