Learn how URL encoding works, when to decode URLs, and how to avoid broken links, unsafe characters, and query string issues.

What URL encoding means

URL encoding converts characters into a safe format for URLs. Spaces, symbols, punctuation, and non-ASCII characters may need encoding so links and query strings work correctly.

Component vs full URL encoding

Encoding a single query value is different from encoding an entire URL. Component encoding is useful for search parameters, while full URL handling should preserve the protocol, domain, path, and separators.

When decoding helps

Decoding helps you inspect URLs, understand query parameters, debug tracking links, and read encoded text. Be careful when decoding unknown links because they may reveal unsafe or misleading destinations.

URL components often use %20 for spaces, while form-encoded data may use plus signs.

Can encoded URLs contain sensitive information?

Yes. Query strings may contain tokens, IDs, emails, or tracking data, so review links before sharing.
