The world wide web consortium recommends using UTF-8 encoding scheme when working with URLs. Note that, our tool assumes that the input is encoded using UTF-8 encoding scheme. Once your input string is decoded, you can click in the output text area to copy the decoded URL. If the input is not a valid URL encoded string, then the input text area will turn red and the output textarea will be cleared. Get started by typing or pasting a URL encoded string in the input text area, the tool will automatically decode your input string in real time. Some examples of control characters include backspace, carriage return, line feed, vertical tab, horizontal tab etc.URL Decoder is the #1 online tool for decoding URLs. These characters are unprintable and cannot be placed directly inside any URL without encoding. URL Encoding character classificationįollowing is the classification of different types of characters that cannot be placed directly inside URLs -ĪSCII control characters: Characters in the range 0-31 and 127 in the ASCII character set are control characters. We then precede the hex value with percent sign, which gives us the final URL encoded value %40. The ASCII value of in decimal is 64 which when converted to hexadecimal comes out to be 40.

Percent Encoded = '%' HEXDIG HEXDIGįor instance, Let's understand how to URL encode the character To encode we first convert it into a sequence of bytes using its ASCII value. The percent sign is used as an escape character that's why we also refer to URL encoding as Percent encoding. Then each byte is represented by two hexadecimal digits preceded by a percent sign (%) - (e.g. URL Encoding works like this - It first converts the character to one or more bytes.

It is also used in preparing data for submitting HTML forms with content-type application/x-www-form-urlencoded. URL encoding, also known as percent encoding, is a way to encode or escape reserved, unprintable, or non-ASCII characters in URLs to a safe and secure format that can be transmitted over the internet. Alphabets / Digits / '-' / '_' / '~' / '.'Īny other character apart from the above list must be encoded. URLs in the world wide web can only contain ASCII alphanumeric characters and some other safe characters like hyphen ( -), underscore ( _), tilde ( ~), and dot (. What is URL encoding or Percent Encoding?

The world wide web consortium recommends that UTF-8 should be used for encoding.Īpart from the tool, our website also contains various articles about how to encode URLs in different programming languages.

Note that, our tool uses UTF-8 encoding scheme for encoding URLs. Once the URL is encoded, you can click in the output text area to copy the encoded URL. You just need to type or paste a string in the input text area, the tool will automatically convert your string to URL encoded format in real time. URL Encoder is a simple and easy to use online tool for encoding URLs.
