URL encoding, also known as percent-encoding, is a method to convert characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
URL encoding is crucial when dealing with special characters in URLs. It ensures that all browsers can interpret the URL correctly, preventing errors and improving the overall user experience.
Our tool uses JavaScript's built-in encodeURIComponent() and decodeURIComponent() functions to perform URL encoding and decoding. These functions handle the most common URL encoding scenarios efficiently and accurately.
Always encode user input before including it in URLs to prevent injection attacks and ensure proper transmission of data. Be cautious when decoding URLs from untrusted sources to avoid potential security risks.
While our tool uses JavaScript, many programming languages have built-in functions for URL encoding:
