About 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 ASCII code.

When to Use

  • Passing data in URL query strings
  • Form submissions with special characters
  • API requests with dynamic parameters
  • Encoding file paths or names

What this tool does

Percent-encode text for URL components or decode escaped text.

How to use it

Choose the operation and the appropriate component or full-URL mode before converting.

Worked example

Component encoding a b&c gives a%20b%26c.

Limitations and checks

Encoding a whole URL as one component also escapes its separators. Do not repeatedly decode untrusted input; malformed escapes can be rejected.
