Frequently Asked Questions
When should I URL encode?
Encode whenever your URL contains spaces, special characters, or non-ASCII characters. This is essential for query parameters, form data, and API requests.
What characters need encoding?
Spaces, quotes, angle brackets, curly braces, pipes, and most non-alphanumeric characters need encoding. Reserved characters like & and = have special meaning in URLs.
Is my data sent to a server?
No. All encoding and decoding happens entirely in your browser using JavaScript's built-in encodeURIComponent and decodeURIComponent functions.
