What is URL Encoding?

URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Locator (URL). It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. This ensures that URLs can be safely transmitted over the internet.

How to Use URL Encoder/Decoder

  1. Select mode - Choose "Encode" or "Decode" based on your needs
  2. Enter URL or text - Paste the URL or text you want to encode or decode
  3. View results - The converted output appears automatically
  4. Copy output - Use the copy button to copy the result

Frequently Asked Questions

What characters need to be URL encoded?

Characters that need encoding include spaces, special characters like @, #, $, %, &, +, and non-ASCII characters. Alphanumeric characters (A-Z, a-z, 0-9) and some special characters (-, _, ., ~) don't need encoding.

Why do URLs need encoding?

URLs have a limited character set. Special characters must be encoded to prevent them from being misinterpreted as URL delimiters or control characters during transmission.

What is the difference between encode and decode?

Encoding converts special characters to percent-encoded format (e.g., space becomes %20). Decoding reverses this process, converting percent-encoded sequences back to their original characters.
