How to Use the URL Encoder/Decoder
To encode: enter plain text or a URL with special characters in the top field and click "Encode". Special characters like spaces, &, =, and non-ASCII characters are converted to percent-encoded format.
To decode: paste an encoded URL in the bottom decoder tool and click "Decode".
Why Encode URLs?
URLs can only contain certain ASCII characters. Special characters like spaces, symbols, and non-English letters must be percent-encoded to work correctly in web addresses, API requests, and query strings. Proper encoding prevents broken links and data corruption.
Is This Tool Free?
Yes, completely free. Uses JavaScript's native encodeURIComponent/decodeURIComponent functions in your browser. No data leaves your device.
