About the Online URL Encode/Decode Converter
URL encoding, also known as Percent-encoding, is a process where non-ASCII characters, reserved characters, and other data requiring special handling are converted into a format that can be safely transmitted within URLs. In URL encoding, these characters are replaced by a percent sign (%) followed by two hexadecimal digits, which represent the ASCII code value of the original character.
URL decoding is the inverse process of URL encoding, which converts encoded strings back to their original format. During URL decoding, each percent sign (%) and the two hexadecimal digits following it are converted back into the corresponding character.
• Features
Compatibility: Ensures URLs are correctly parsed by various browsers and servers, maintaining the accuracy of information transmitted over the Internet.
Security: By encoding sensitive characters such as spaces and special symbols, it prevents the information from being misinterpreted or maliciously exploited.
Reversibility: URL encoding is a reversible process, allowing encoded URLs to be completely decoded back to their original state.
• Use Cases
Including secure data in URLs: When URLs need to include special or reserved characters, such as spaces, &, or # in query strings, these characters are encoded to prevent confusion.
Cross-language support: URL encoding ensures that non-English characters are correctly transmitted and interpreted, supporting the sharing of multilingual content.
Form data submission: When submitting web forms, if the form data contains special characters, this data is URL encoded to ensure safe transmission to the server.
Preventing XSS attacks: By encoding scripts or other potentially malicious content inserted into URLs, the risk of cross-site scripting (XSS) attacks is reduced.
