What is URL Encoding?

URL encoding converts characters into a format that can be transmitted over the internet. Special characters are replaced with a % followed by two hexadecimal digits.

Examples:

space%20
&%26
=%3D

What is 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 numeric value.

Why is URL Encoding Necessary?

URLs can only contain certain characters from the ASCII character set. Special characters like spaces, ampersands, equals signs, and non-ASCII characters must be encoded to be safely transmitted over the internet.

Common Use Cases

  • Query Parameters: Encoding search terms and filter values in URLs
  • Form Data: Encoding form submissions in GET requests
  • API Requests: Safely passing parameters to APIs
  • SEO: Creating clean, readable URLs with special characters
  • OAuth: Encoding redirect URLs and state parameters

Encoding Examples

Original:
Hello World!
Encoded:
Hello%20World%21
Original:
user@example.com
Encoded:
user%40example.com
Original:
name=John Doe&age=30
Encoded:
name%3DJohn%20Doe%26age%3D30

Frequently Asked Questions

When should I use URL encoding?

Use URL encoding whenever you need to include special characters or non-ASCII characters in a URL, especially in query parameters or form data.

What's the difference between URL encoding and Base64?

URL encoding is specifically designed for making text URL-safe by encoding special characters. Base64 is for encoding binary data into ASCII text. Use URL encoding for URLs and query parameters, Base64 for binary data.

Does URL encoding encrypt my data?

No. URL encoding is not encryption. It simply transforms characters into a URL-safe format. Anyone can decode URL-encoded strings.

Can I encode entire URLs?

Yes, but typically you only encode the query parameters or path segments, not the protocol (http://) or domain name. Our tool will encode whatever you input.
