What is URL Encoding?

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits representing the character's byte value.

For example, a space character becomes %20, and an ampersand (&) becomes %26. This ensures that the URL can be transmitted safely over the internet without any characters being misinterpreted as URL delimiters or special characters.

Common URL Encodings

  • Space→ %20 or +
  • !→ %21
  • #→ %23
  • $→ %24
  • &→ %26
  • =→ %3D
  • ?→ %3F
  • @→ %40

Common Use Cases for URL Encoding

Frequently Asked Questions

What is URL encoding?

URL encoding converts special characters into a format safe for URLs using percent signs followed by hexadecimal values (e.g., space becomes %20).

Why do I need to encode URLs?

URLs can only contain certain ASCII characters. Special characters, spaces, and non-ASCII text must be encoded to prevent errors and ensure proper transmission.

Is this tool free to use?

Yes, completely free with no limitations, registration, or hidden costs. Encode and decode unlimited text anytime you need.

What's the difference between + and %20?

Both represent spaces, but + is used in query strings (application/x-www-form-urlencoded) while %20 is the standard percent-encoding used elsewhere in URLs.

Does it support Unicode?

Yes! Our tool fully supports Unicode characters including emojis, special characters, and text in any language using UTF-8 encoding.
