What Is URL Encoder?

URL encoding (percent-encoding) converts unsafe characters into a safe format for URLs and query strings.

What is URL encoding?

Characters that are unsafe in URLs — spaces, &, ?, #, and non-ASCII characters — are replaced with a % followed by their hex code. Component encoding also encodes reserved characters like /.

When to encode

Encode query parameter values to prevent breaking URLs, and encode user input before adding it to links.

Key Features

  • Percent-encoding
  • Component and full-URL modes
  • Local processing

Examples

  • "hello world" becomes "hello%20world".

Common Use Cases

  • Building query strings
  • Encoding user input
  • API requests

Tips & Best Practices

  • Use component encoding for individual parameter values.

Limitations

  • Encoding full URLs can double-encode existing % sequences.
