URL Encoder / Decoder

URL encoding, also known as percent-encoding, is a fundamental mechanism for formatting information in a Uniform Resource Identifier (URI) or URL. It's the process of converting characters, especially "unsafe" or reserved characters, into a format that can be safely transmitted over the Internet. URLs are restricted to a limited subset of the ASCII character set. Any character outside this set, such as spaces, ampersands, or non-English characters, must be encoded to ensure the URL is correctly interpreted by web servers and browsers.

This tool provides a quick and reliable way to perform both encoding and decoding operations. Whether you're constructing a complex URL with dynamic query parameters or trying to decipher an encoded string from a log file, this utility simplifies the process. All conversions happen instantly in your browser, keeping any potentially sensitive data in your URLs completely private.

How it Works:

The encoding process replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits that represent the character's ASCII value. For example, a space character is encoded as %20, an ampersand (&) as %26, and a plus sign (+) as %2B.

• Encode: Converts a regular string into a URL-safe string. This is essential when you need to include user-generated text or special characters in a URL query parameter. Paste your text and click "Encode."
• Decode: Converts a URL-encoded string back into its original, human-readable format. This is useful for analyzing incoming request URLs or debugging. Paste the encoded string and click "Decode."
