URL encoder is a tool that converts characters into a format that can be quickly and securely transmitted over the Internet. URLs can only be transmitted through the Internet with the help of the ASCII character set.
URLs (Uniform Resource Locators) often have loads of characters and values outside the ASCII, so we must convert the URL into a valid ASCII format for successful transmission. URLs cannot have spaces in them, so even those are replaced with a plus symbol (+) or a "%20".The encoding process also replaces the characters outside the ASCII format with a percent "%" followed by two hexadecimal digits. It is called URL encoding, and it is mostly used within the main Uniform Resource Identifier (URI). URI includes Uniform Resource Name (URN) and Uniform Resource Locator (URL).
An URL encoder is a simple online tool that can easily encode URLs into its ASCII set accepted format. The encoded data is thus allowed to be transmitted over the Internet. It is a free online tool where you can manually enter the URL or load the URL directly from the source and encode it by using the tool. The results will be visible in a matter of seconds. It is quite a handy tool and saves the hassle of doing it manually.
