Url Encoder and Decoder: Why do you need this tool?

encoder and decoder

URL encoding is an important procedure to convert a string into a valid URL layout. A valid format means that a URL must have alpha, safe, digit, escape and extra characters. URL encoding is performed to convert data passed through HTML forms. This type of data may have special characters, such as “,”, “/”, “#”, and have special meanings.

These characters are not valid for URLs. It is possible to alter them during transfer. For example, the hash “#” character needs encoding because it has a particular meaning of HTML anchor. The <space> character needs encoding because it may not allow a valid format of URL. Some characters like “~” may not correctly transport through the internet.

While URL Encoding, you have to deal with <form>s. From different methods (POST and GET) perform implicitly for URL Encoding. Websites use POST and GET means to pass strictures between different HTML pages. You can use any encoder and decoder tool to verify your HTML pages.

URL Encoder and Decoder Tools

This tool can convert a text string into a suitable form for inclusion in one URL. This form is known as URL encoding or percentage encoding. The device can convert an encoded cord back.

Uses of URL Encoder and Decoder Tool

For encoding, enter text in a text box that you want to include in the parameter of URL. Click “URL button” and “Go”. You shouldn’t give one full URL to this tool; otherwise, you will not get accurate results.

For decoding: Enter your URL-encoded text in a text box. It may be a part of URL or full URL. Click on a URL encode button and finally “Go”.

A URL may contain essential parameters that include syntactic markers. If they are entered without any change, the browser may parse them erroneously. For instance, you might get one URL with a parameter.

Text=one two three

If it goes in a URL without any change: http://www.abc.com?text=one two three

You can use this URL in one link; the server may have trouble because space terminates a URL. With URL encoding, you can convert unsafe characters into an encoded form. The tool is useful to find a URL with important encoded characters in the file. You can see the final look of URL with plain texts. URL encoding is used for cookie values in data and HTTP headers in POST requests.

What does a tool do?

The tool for URL encoding takes one string and changes it to URL-encoded format. It is known as a percentage encoding. It treats non-ASCII characters as UTF-8. The decoding tool of URL takes one string with URL encoded characters and changes the code back to unencoded format.

  • The URL encoding term is common but erroneous. The encoding applies to a general category of URIs (Uniform Resource Identifiers), including URNs (Uniform Resource Names). Parameter values of URL may include alphanumeric ASCII characters without trouble. Certain typescripts are reserved and should be encoded to ensure accurate interpretation of a URL.
  • The URL encoding must not be done except in specific parameter values. The characters must be encoded by substituting it with one percent sign followed by hexadecimal two-digit encoding.
  • All characters (other typescripts than safe ones) are replaced in one URL encoding. The safe characters are lower and upper case ASCII letters, the characters, and digits. For instance, $ – _. + ! * ‘ ( ).
  • All characters including some non-printing characters and other outside ASCII 7-bit must be URL encoded for safety. Other characters may be URL encoding, but there are some risks and zero benefits. If the server software is not expecting any encoded characters without decoding them, it may not work correctly. It can be a bug without risk of buggy behavior. Only a tester can analyze the buggy behavior.
  • URL encoding and decoding are necessary for domain name section of one URL. There is no need to use an encoding tool for the conversion of domain names. It will convert periods and break a URL.
  • The URL encoding can increase the length of the URL. The URL is free from any official limit, but 2000 characters can be a safe length. If a URL is exceeding 2000 characters, you can go with the POST instead of a GET demand.
  • The URL encoder and decoder get UTF-8 text or ASCII. The encoding doesn’t assume a character set. It may take bytes that a server may interpret while programming it. These are interrupted as Latin-1, UTF-8 or others. Some websites expect UTF-8. A few old sites may interpret parameters of URL in Microsoft Windows-1252, Latin-1 and encoding.
  • Values from %00 (0) to %FF (255) may be encoded by URL, so binary data is passed in the URL parameter. This type of data may not have byte encoding. It is efficient to pass “A” as hex 41 instead of “%41”.
  • The tool must be used for single URL structures. Encoding a URL or parameter string may encode particular characters like “=” and “?” making them standard text instead of URL syntax. HTTP POST accepts form fields instead of considering them as a part of URL. It looks similar to queries and has no limit for length. It utilizes the encoding of URL in the same way.

HTTP headers avoid cookies with some characters to stay away from syntactic problems. It may not hurt the standard encoding and slightly increase the size of data. It is safe to use an URL encoder and decoder to decode a URL. The parameter values must use encoding while leaving other things. Your work can be easy with the use of url encoder and decoder tool.
