URL Encoder/Decoder - Online URL Tool

What is URL Encoding?

URL encoding (also known as percent-encoding) is a mechanism for converting special characters into a format that can be safely transmitted in URLs.

Why is URL Encoding Needed?

• URLs can only contain a subset of ASCII characters
• Certain characters have special meanings in URLs (such as ?, &, =, etc.)
• Non-ASCII characters (such as Chinese) need to be encoded for use in URLs

Common Use Cases

• Passing Chinese or special characters in URL parameters
• Processing form submission data
• API interface parameter passing
• Search engine query strings
