About URL Encoding

URL encoding (percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It's commonly used for:

  • Encoding special characters in URL parameters
  • Transmitting data safely in web addresses
  • Handling spaces and non-ASCII characters in URLs
  • Building API query strings

About URL Encoder & Decoder

Our free URL encoder and decoder tool helps you encode text to URL format or decode URL-encoded strings back to text instantly. URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). This is essential for web developers and anyone working with APIs and web addresses.

What is URL Encoding?

URL encoding is used when placing text in a URL. Characters that are not allowed in a URL must be encoded. This includes spaces, special characters like &, ?, =, and non-ASCII characters. These characters are replaced with a % followed by their two-digit hexadecimal representation.

For example, a space is encoded as %20, and the & character is encoded as %26.

Frequently Asked Questions

Why do I need to encode URLs?

URLs can only contain a limited set of ASCII characters. Special characters like spaces, brackets, or ampersands have specific meanings in URLs (like separating parameters). If you want to include these characters as actual data, they must be encoded so the browser or server doesn't misinterpret them.

Is this tool safe to use?

Yes, absolutely. All encoding and decoding happens locally in your browser using JavaScript. No data is ever uploaded to our servers, ensuring your information remains private and secure.

Does this tool handle Unicode characters?

Yes, our URL encoder/decoder fully supports Unicode characters, including emojis and international scripts, correctly encoding them into percent-encoded format according to the URI standard.
