URL Encode & Decode

What is URL Encode & Decode?

URL Encode and Decode converts text to percent-encoded form and restores encoded sequences to readable characters. It helps inspect query parameters, path fragments, redirects, callback URLs, and copied request data where reserved characters or Unicode must travel safely within a URL component.

How to use URL Encode & Decode

Enter text or an encoded URL value, choose encode or decode, and copy the transformed result.

When is URL Encode & Decode useful?

URL Encode & Decode is useful when preparing query parameters, debugging URLs, checking percent-encoded values, or translating encoded text back into readable form.

Example

A practical example is encoding a query value that contains spaces and symbols before placing it in a URL.

Practical notes

Encode individual components rather than blindly encoding an entire URL, because separators such as slashes, question marks, ampersands, and equals signs have structural meaning. Decoding untrusted values does not make them safe for HTML, SQL, shells, or redirects.
