Frequently asked questions

Does it count spaces?
Yes by default, with a toggle to exclude them if you only want visible-character length.
Is it free to use?
Yes, completely free.
Is my data uploaded anywhere?
No, the count is calculated entirely in your browser.
Does it handle emoji and other unicode characters correctly?
It counts based on characters, though some emoji made of multiple code points (like flags or skin-tone variants) can count differently than they visually appear as one character.
How is this different from Word Counter?
This tool is purely about character length; Word Counter also gives you word, sentence, and paragraph stats.
