About the URL Encoder/Decoder
Safely convert reserved characters into percent-encoded values or decode an existing URL into readable text. Advanced views help parse URL components and construct query strings without manually managing separators and escaping.
Common uses
- Prepare query parameters containing spaces and reserved characters.
- Decode a long URL while debugging a redirect or API request.
- Build a query string from key-value pairs without escaping errors.
URL Encoder/Decoder questions
When should I encode a URL component instead of a full URL?
Encode individual parameter values when preserving separators such as ?, &, =, and /. Full-URL encoding is appropriate only when the entire URL is itself a value inside another context.
Why are spaces sometimes encoded as plus signs?
HTML form encoding commonly represents spaces as +, while standard percent encoding represents them as %20.
