What is URL Encoding?

URL encoding, also known as percent-encoding, converts characters that are not allowed in a URL into a format that can be safely transmitted over the internet. Since URLs can only contain a limited set of ASCII characters, special characters such as spaces, punctuation marks, and non-ASCII characters must be encoded.

Each character is replaced by a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code. For example, a space becomes %20, and & becomes %26.

Common Use Cases

• Query parameters: Encoding values in URL query strings (e.g.,?name=John%20Doe).
• Form submissions: Encoding form data before sending it via GET or POST requests.
• API calls: Ensuring that special characters in API endpoint parameters do not break the request URL.
• Sharing links: Making URLs safe to share in emails, messages, or documents without losing special characters.

Example

Input:

Hello World! & welcome=true

URL encoded output:

Hello%20World!%20%26%20welcome%3Dtrue
