URL encoder is an online tool that encodes URL text into a human-readable encoded format accurately and quickly. Also, it is more generally used within the Uniform Resource Identifier (URI) set and it includes Uniform Resource Name (URN) and Uniform Resource Locator (URL). In addition, it is used in the preparation of data of the "application/x-www-form-urlencoded" media type.
Even if you are a technical or non-technical person, the URL encoder is very simple to use. All you need to do is just type or paste the URL string in the input area and press the "Encode" button. As a result, the tool will automatically convert the text string into its URL encoded format and display it below.
A URL consists of different parts. Some are compulsory and others are optional. They are discussed below.
URL encoding is a procedure for translating special characters into the universally accepted format by web servers and browsers. Generally, URLs contain ASCII alphanumeric characters and other safe characters like hyphen(-), underscore (_), dot(.), and tilde(~). These characters are not changed during the encoding process.
It is a way to encode reserved, unprintable, or non-ASCII characters in URLs into a safe and secure format that can be further transmitted over the Internet. Most importantly, URL encoding is commonly used in HTML form data submission in HTTP requests. Also, you can use our URL Encoder to do this encoding process quickly and accurately without any technical knowledge.
It's a two-step process. The first step involves the conversion of the character to one or more bytes. In the second step, each such byte is represented by two hexadecimal digits starting from a percent sign (%).
The percent sign acts as an escape character. So, URL encoding is also known as percent-encoding.
Let's understand this with an example.
Take any character, suppose @.
Follow the steps below.
So, the URL encoded value is %40.
The different types of characters that cannot be placed directly in URLs are as follows:
The only class of characters that do not need encoding are safe characters. It includes alphabets, both uppercase(A-Z) and lowercase(a-z), digits(0-9), hyphen (-), underscore (_), tilde (~), and dot(.).
Some common ASCII characters and their corresponding URL encoded value is as below.
As per the URL specification RFC 187, only a limited set of characters are allowed to be used in a URL, and the rest other characters must be encoded before including them in the URL. That's where the URL encoding is used.
All characters that are not allowed to be directly placed in the URL must be replaced by the percent sign (%) and a two-digit hexadecimal value. This value signifies the character in the appropriate ISO character set. For example, $ becomes %24 and + becomes %2B.
Characters acceptable in URI are either reserved or unreserved. Reserved characters are those that have a special meaning. For example, slash character. Unreserved characters do not have any special meaning.
Yes, we can. The percent character acts as the sign for URL encoded octets. So, it must be encoded as %25.
No, you can't use it offline. Because it's an online tool and you need an active internet connection to use it.
