URL percent-encoding is a fundamental mechanism used to encode special characters in URLs. When you see characters like %20 or %26, these represent the percent-sign (%) followed by hexadecimal values that correspond to specific characters.
UTF-8 decoding is essential for handling international characters in URLs. Our tool fully supports UTF-8 encoded content, allowing you to decode URLs containing characters from any language, including Chinese, Japanese, Arabic, and emoji characters.
is crucial for web development. A URL consists of several parts: protocol, domain, path, query parameters, and fragment. Each component may require encoding when containing reserved characters like URL components ?, &, =, #.
REST API debugging. When working with APIs, you often encounter encoded query parameters or path segments. Being able to quickly decode these URLs helps identify issues in API requests and understand the actual data being transmitted.
URL decoding (also known as percent-decoding) is the process of converting encoded characters in a URL back to their original form. When data is transmitted via URLs, special characters are replaced with a percent sign (%) followed by two hexadecimal digits. For example, %20 represents a space character, and %26 represents an ampersand (&).
Simply paste your encoded URL into the input field at the top of this page. Our tool automatically decodes the URL in real-time as you type, showing the result instantly. You can then copy the decoded result with one click. No registration, payment, or software installation required.
Percent-encoding (also called URL encoding) is a mechanism for encoding information in URLs using only the limited ASCII character set. Special characters are replaced with a percent sign (%) followed by their hexadecimal ASCII value. This ensures URLs can be safely transmitted across all systems without data corruption.
URLs can only contain a limited set of ASCII characters. Special characters like spaces, ampersands, question marks, and non-ASCII characters (such as UTF-8 international text) must be encoded to be safely transmitted in URLs. This ensures URLs work correctly across all browsers, servers, and systems worldwide.
