What is URL Encoding?

URL encoding (also called percent encoding) converts special characters, spaces, and non-ASCII characters into a format that can be safely transmitted in URLs.
Common encoded characters include:
  • Space → %20
  • & → %26
  • = → %3D
  • # → %23
  • @ → %40
  • / → %2F (when encoding components)

Our encoder supports both JavaScript encoding methods:
  • encodeURIComponent() - Encodes all special characters (use for query parameters)
  • encodeURI() - Encodes URI but preserves reserved characters like :, /, ?, &, =, #, @
encodeURIComponent Use for encoding individual URL components like query parameter values
  • Example: `encodeURIComponent('hello world')` → `hello%20world`
  • Use when encoding values that will be placed in query strings

encodeURI: Use for encoding entire URLs while preserving structure
  • Example: `encodeURI('https://example.com/path?q=hello world')` → `https://example.com/path?q=hello%20world`
  • Preserves :, /, ?, &, =, #, @ characters

When to Use Each Method

Query Parameter Encoding

Our tool includes an option to encode only query parameters while preserving the URL structure.

This is perfect for:
  • Encoding parameter values without breaking URL structure
  • Preserving domain and path while encoding query strings
  • Maintaining readable URLs with encoded parameters
