URL Encoder & Decoder

URL encoding (also called percent-encoding) converts characters that are not allowed in URLs into a safe %XX format. This tool helps encode or decode query strings and URIs entirely in the browser.

Common use cases

• Encode special characters in query parameters or form data
• Decode mangled URLs from logs, emails or copied text
• Fix or inspect percent-encoded values from APIs or redirects
