URL Encode and Decode are two online tools that allow users to encode or decode any URL string easily and efficiently. URL encoding is the process of converting a URL into a valid format that can be safely transmitted over the internet. This is done by replacing any reserved characters, such as spaces or question marks, with their corresponding URL-encoded equivalents. URL decoding, on the other hand, is the process of converting a URL-encoded string back into its original form. This is necessary when receiving data from a web server that has been encoded in a URL-safe format. By using the URL Encode and Decode tools, users can quickly and easily encode or decode any URL string as needed.
