About URL Decode

URL decoding is the process of converting percent-encoded characters within a URL or URI back to their original, readable form. This reverse process of URL encoding is necessary because URLs can only contain a limited set of characters from the ASCII character set. Special characters, including spaces and punctuation marks, are percent-encoded to ensure the integrity and reliability of web communication. URL decoding interprets these percent-encoded sequences and restores the original characters they represent.

For example, in a URL-encoded string, the space character is represented as %20, and the plus symbol (+) is often used to encode a space in application/x-www-form-urlencoded data. During URL decoding, these representations are converted back to a space character. Similarly, other encoded characters, like %2C for a comma or %3F for a question mark, are decoded back to their original forms (, and ?, respectively).

What is URL Decode Tool ?

URL Decode is a free online tool designed to convert percent-encoded parts of a URL or URI back into their original, human-readable format. This process is essential in web development and internet communication because URLs are limited to a certain set of characters. When a URL includes characters outside this set (like spaces or certain punctuation marks), those characters are percent-encoded to ensure the URL remains valid. URL decoding reverses this encoding, restoring the data to its original form.

Here's how a URL Decode Tool typically works:

  1. Input: You input a percent-encoded URL.
  2. Decoding Process: The tool scans the input for percent-encoded sequences—each consisting of a percent sign (%) followed by two hexadecimal digits—and replaces each sequence with the corresponding ASCII or UTF-8 character.
  3. Output: The tool outputs the decoded URL, which translates the percent-encoded sequences back to their original characters.

For example, if you input Hello%20World%21, a URL Decode Tool would output Hello World!, translating %20 back to a space and %21 back to an exclamation mark.
