Encode special characters for URLs or decode encoded URLs.
Encode special characters for safe use in URLs, or decode percent-encoded URLs back to readable text. Essential for web developers building query strings, API integrations, and redirect rules. Handles spaces, ampersands, unicode characters, and all reserved URL characters.
URLs can only contain certain ASCII characters. Spaces, ampersands (&), equals signs (=), question marks (?), and non-ASCII characters (like accented letters or emoji) must be encoded as percent-encoded sequences (e.g., space becomes %20, & becomes %26). Without encoding, these characters break the URL structure or get misinterpreted by web servers.
