What is URL Encoding?

URL encoding (also called percent encoding) is a mechanism for encoding information in a URL. It is used to convert characters that have special meaning in URLs into a format that can be safely transmitted over the internet. When you have special characters in a URL, they need to be encoded using the percent sign (%) followed by two hexadecimal digits.

Why Use URL Encoding?

  • Reserved Characters: Some characters like ?, &, =, and # have special meanings in URLs and must be encoded when used as data.
  • Unsafe Characters: Spaces and other characters cannot be transmitted directly in URLs and must be encoded.
  • International Characters: Non-ASCII characters must be encoded to ensure compatibility across systems.
  • API Compatibility: Many APIs require URL-encoded parameters for proper data transmission.

Common URL Encoding Examples

Space

Plain: hello world
Encoded: hello%20world

Question Mark

Plain: what?
Encoded: what%3F

Ampersand

Plain: a&b
Encoded: a%26b

Equals Sign

Plain: key=value
Encoded: key%3Dvalue

encodeURI vs encodeURIComponent

encodeURI()

Used for encoding complete URLs. It does NOT encode reserved characters like :, /, ?, #, &, =, which are needed for URL structure.

encodeURI("https://example.com/search?q=hello world")
→ https://example.com/search?q=hello%20world

encodeURIComponent()

Used for encoding URL components (query parameters, path segments). It encodes ALL special characters including :, /, ?, #, &, =.

encodeURIComponent("hello world")
→ hello%20world
