Ascii url encoder
World's simplest ascii tool
A simple browser-based utility that URL-encodes ASCII characters. Just paste your ASCII text in the input area and you will instantly get percent-encoded ASCII in the output area. Fast, free, and without ads. Import ASCII – get URL-escaped ASCII. Created by computer nerds from team Browserling.

What is a ascii url encoder?
learn more about this tool
This tool takes ASCII as input and applies URL-encoding on it. This encoding finds all special ASCII characters in the data and converts them into hex values with a percent sign. Therefore, URL-encoding is often called the percent coding. Depending on the set of special characters, there are several encoding methods. The encode-uri function encodes all ASCII characters except digits, uppercase Latin letters, lowercase Latin letters, and symbols "!#$&'()*+,-./:;=?@_~". The encode-uri-component method encodes all ASCII symbols except digits, letters, and the following 9 symbols "!'()*-._~". The escape method also doesn't encode numbers, letters, and 7 more characters "*+-./@_". The alphanum-underscore method preserves numbers, letters, and the "_" character and escapes all other symbols. If none of these methods suit you, you can create your own method. To do this, you can select the option "Custom Encoding Characters" or option "Custom Non-encoding Characters", and enter the required ASCII characters in the field below. If the first option is selected, then the specified symbols will be encoded (and all others won't be). If the second option is selected, then the specified characters will not be encoded (and all others will be). We have also added a separate group of options to control whitespace symbols. Using these options in the second options group, you can skip encoding newlines, tabs, or spaces. The third group of options allows you to choose the letter case for hexadecimal values. For example, an asterisk character "*" can be escaped as "%2a" (lowercase hex) or "%2A" (uppercase hex). Asciiabulous!
Ascii url encoder examples
Click to useHello World Example
In this example, we URL-encode an ASCII string that says hello world. We use the "Escape" encoding method that encodes spaces, exclamation and quote marks, all types of brackets (and 26 other ASCII characters that aren't used here). As they say, simple examples are the best examples.
"(Hello world!)"
%22%28Hello%20world%21%29%22
Required options
What URL-escaping shall we use?
Skip newlines during encoding.
Skip tabs during encoding.
Skip spaces during encoding.
Display hexadecimal
values in lowercase.
URL-Encode Newlines
This example loads ASCII data with three variables x, y, and z, and encodes them using the "AlphaNum_" function. This function escapes all symbols that are not alphanumeric or underscore. In the example variables x, y, and z are all alphanumeric, so they remain untouched. Only the newline characters are encoded into their lowercase hexadecimal representations "%0a".
x
y
z
x%0ay%0az

Percent-encode a URL
In this example, we percent-encode an FTP link that contains many special URL symbols. We apply the component encoding function on this link and convert the column character and all slashes to URL-escaped sequences with hex digits in uppercase format.
ftp://ftp.tucows.com/software/dreamweaver
ftp%3A%2F%2Fftp.tucows.com%2Fsoftware%2Fdreamweaver
Required options
What URL-escaping shall we use?
Skip newlines during encoding.
Skip tabs during encoding.
Skip spaces during encoding.
Display hexadecimal
values in uppercase.
Encode Everything Except Newlines
In this example, we have selected a two option combo. The first option encodes all ASCII characters and the second option "Do Not Encode Newlines" makes a slight exception to this rule and skips encoding \n symbols. This way each French word is percent-encoded and remains on its own line.

%64%65%75%78
%74%72%6f%69%73

Skip spaces during encoding.

Custom Encoding Characters
In this example, we encode three ASCII strings that contain the charge data of elementary particles. We escape the strings via the "Custom Encoding Characters" option. In the textbox for custom characters, we enter digits from 0 to 3 and the dot character. In the output, only the entered symbols are escaped.
1. Electron: -1 e;
2. Proton: 1 e;
3. Neutron: 0 e;
%31%2e Electron: -%31 e;
%32%2e Proton: %31 e;
%33%2e Neutron: %30 e;
Required options

Skip newlines during encoding.
Skip tabs during encoding.
Skip spaces during encoding.

values in lowercase.
Custom Non-encoding Characters
This example uses the "Custom Non-encoding Characters" option to escape data in a list of antonyms. In the text field for this option, we have specified the uppercase ASCII letters and the en dash symbol. What this means is that all characters except these will be escaped. Additionally, we have selected three whitespace preserving options that skip escaping newlines, tabs, and spaces, and selected another option that prints the hexadecimal percent codes in uppercase.
