What is URL Encoding?

URL encoding (also called percent encoding) converts characters into a format that can be safely transmitted over the internet. Special characters, spaces, and non-ASCII characters are replaced with a "%" followed by two hexadecimal digits.

Common Use Cases

Encode query parameters in URLs
Encode form data for HTTP requests
Handle special characters in API calls
Decode URL-encoded data from logs
Create safe URLs with user-generated content
Debug web application URLs

Character Encoding Examples

Character	Encoded	Use Case
Space	%20	Separating words in URLs
&	%26	Query parameter values
=	%3D	Query parameter values
?	%3F	Part of parameter values
/	%2F	Path separators in values
@	%40	Email addresses

Frequently Asked Questions

When should I URL encode?

Always encode query parameter values that contain special characters, spaces, or non-ASCII characters. For example: ?search=hello world should be ?search=hello%20world

What's the difference between + and %20 for spaces?

Both represent spaces, but in different contexts. %20 is the standard URL encoding for a space. The + character is used in form data (application/x-www-form-urlencoded). Our tool uses %20 (the standard).

Can I encode the entire URL?

You typically encode only specific parts (like query parameters or path segments), not the entire URL. Encoding https:// would break the URL structure.

Real-World Example

Original URL with problematic characters:

https://example.com/search?q=hello world&category=tools & utilities

Properly encoded URL:

https://example.com/search?q=hello%20world&category=tools%20%26%20utilities
