Frequently Asked Questions

How do I URL encode a string online?

Paste your text into the input box and click Encode. Special characters like spaces, &, =, and non-ASCII characters are converted to percent-encoded format (%20, %26, etc.).

What is URL encoding (percent encoding)?

URL encoding replaces unsafe characters with a % followed by two hex digits (e.g., space becomes %20). This ensures strings are safe for use in URLs and query parameters.

When should I URL encode?

URL encode when including user input in URLs, building query parameters, or passing special characters in API requests. Characters like &, =, ?, #, and spaces must be encoded.
