URL Encoder and Decoder Online

URLs can only contain certain characters. Encoding replaces unsafe characters with "%" followed by hex digits.

When to Encode

• Query parameters - Sending data in URLs
• Special characters - Spaces, slashes, etc.
• API calls - Constructing valid requests

Common Encodings

• Space -> %20
• / -> %2F
• ? -> %3F
• & -> %26

Decoding

Decoding reverses the process, turning "%20" back into a space, making URLs readable again.
