About URL Encoder/Decoder

The ZamDev URL Encoder/Decoder converts special characters in URLs to their percent-encoded equivalents and back. When URLs contain spaces, ampersands, non-ASCII characters, or other special symbols, they must be encoded for proper transmission across the internet. This tool handles both full URL encoding (encodeURI) and component encoding (encodeURIComponent) so you always get the right encoding for your use case.

  2. 2Choose between full URL encoding or URI component encoding.
  3. 3Click Encode to convert special characters to percent-encoded format.
  4. 4Or paste an encoded URL and click Decode to reveal the original.
  5. 5Copy the result for use in APIs, query strings, or web applications.
