About URL Encoder/Decoder

URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Our free online tool allows you to safely encode special characters in URLs or decode percent-encoded strings back into readable text, all within your browser.

How It Works

URL encoding works by replacing unsafe ASCII characters with a '%' followed by two hexadecimal digits representing the character's ASCII value. For example, a space becomes '%20', and an ampersand '&' becomes '%26'. This ensures the URL is valid and can be transmitted over the internet.

Common Use Cases

  • Encoding query parameters in a URL to ensure special characters don't break the link
  • Decoding a complex URL to read its parameters and values clearly
  • Preparing data to be sent via HTTP GET or POST requests
  • Fixing broken links caused by unencoded spaces or special characters

Frequently Asked Questions

Safe characters include alphanumeric characters (A-Z, a-z, 0-9) and a few special characters like hyphen (-), underscore (_), period (.), and tilde (~). All other characters should be encoded.

encodeURI is used for full URLs and doesn't encode characters that have special meaning in a URL (like :, /, ?, &, =). encodeURIComponent is used for individual query parameters and encodes almost everything, including those special characters.
