Frequently Asked Questions
What is URL encoding?
URL encoding converts special characters like spaces, &, =, and ? into percent-encoded format (e.g., space becomes %20) so they can be safely used in URLs.
When do I need to decode a URL?
When you receive a URL-encoded string from an API, form submission, or query parameter, decoding reveals the original readable text.
