Frequently Asked Questions

      
Also called percent-encoding, it replaces characters that aren’t URL-safe with %XX sequences, like a space becoming %20.
Component encoding (encodeURIComponent) escapes everything; whole-URL encoding (encodeURI) preserves URL structure characters like / : ? & =.
No — encoding and decoding run in your browser.

    

    

      
URL-encode and decode text online for free. Percent-encode a value so it is safe inside a URL — spaces become %20, and other special characters get their %XX equivalents — or decode an encoded string back to plain text. Choose component encoding to escape everything, or whole-URL mode to keep the structure characters like slashes and query separators. Everything runs in your browser, so it is fast and private.
