Paste or type your text into the box and the character count updates instantly. The tool also shows the number of words, lines, and non-whitespace characters. Everything runs in your browser, so your text is never uploaded to a server.
Yes. The main string length includes every character, including spaces, tabs, and line breaks. A separate non-whitespace count is also shown if you want the length excluding spaces and other whitespace.
This calculator counts characters (Unicode code points as seen by JavaScript). For plain ASCII text one character equals one byte, but characters like emoji or accented letters can take multiple bytes when encoded as UTF-8, so the byte length may be larger than the character length.
There is no fixed limit. Because counting happens locally in your browser, you can paste very large blocks of text and still get an instant count, limited only by your device's memory.
