Url Encoder/Decoder

URL encoding (also called percent encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and non-ASCII characters are replaced with a percent sign (%) followed by their hexadecimal code. For example, a space becomes %20.

Simply paste or type your URL into the input field and click the "Encode" button. The tool will automatically convert all special characters to their percent-encoded equivalents. You can also encode individual components or query parameters separately.

Paste your encoded URL (with percent-encoded characters) into the input field and click the "Decode" button. The tool will convert all percent-encoded sequences back to their original characters, making the URL human-readable again.

Common characters that need encoding include:

• Spaces → %20
• Ampersand (&) → %26
• Plus (+) → %2B
• Equals (=) → %3D
• Hash (#) → %23
• Question mark (?) → %3F
• And other special or non-ASCII characters

URLs are stored locally in your browser's storage for convenience (so you can access your history), but they never leave your device. All encoding and decoding happens entirely in your browser, ensuring complete privacy and security.

Yes! You can encode or decode individual query parameters or URL components. Simply paste the specific part you want to process (like a parameter value) into the input field, and the tool will handle it accordingly.

When encoding an entire URL, only the necessary parts (like query parameters and path segments) are encoded, while the protocol, domain, and other structural parts remain unchanged. When encoding individual parameters, all special characters in that specific value are encoded. This tool handles both scenarios automatically.
