Char Frequency is a free, private online tool that lets you count how often each character appears in text, sorted by frequency. It runs entirely in your browser, so nothing you enter is uploaded to a server.
Privacy: this tool runs entirely in your browser. Your input is never sent to, received by, or stored on any server — there are no uploads and no tracking of what you enter.
It tallies every character — letters, digits, spaces and punctuation — and lists them by how often they occur.
Frequency analysis for puzzles and ciphers, checking text composition, and data cleaning.
Whitespace characters are labeled (space, newline, tab) so the counts are clear.
A character frequency counter tallies how many times each character appears in a piece of text and lists them from most to least common. Every letter, digit, space and punctuation mark is counted, giving you a precise breakdown of a text's composition.
The tool scans your text and keeps a running count for each distinct character, then sorts the results by frequency. Whitespace characters are clearly labelled (space, newline, tab) so the counts are easy to read rather than showing invisible gaps. The output is a ranked frequency table.
Character frequency is the foundation of classic cryptanalysis. In any language, letters appear with characteristic frequencies - in English, E, T, A and O are most common. By comparing the frequencies in an encrypted message to those expected in plain text, codebreakers can crack simple substitution ciphers (like Caesar or Atbash). This tool is a hands-on way to explore that technique.
Beyond puzzles and ciphers, frequency counting helps analyse text composition, detect unusual or unexpected characters (such as hidden control characters or the wrong kind of quote), study writing patterns, validate data, and support linguistics and data-cleaning tasks. It reveals at a glance what a text is actually made of.
Paste or type text and the frequency table updates instantly, sorted by how often each character occurs. Counting is case-sensitive, so uppercase and lowercase are tallied separately. Everything runs in your browser.
