Character Frequency Counter Online
Count how often each character or word appears in text, sorted by frequency, entirely in your browser.
The Character Frequency Counter runs entirely in your browser. The text you paste is analyzed locally and never leaves your device or gets uploaded to ArrayKit.
The Character Frequency Counter tallies how often each character or word appears in a block of text and sorts the results from most to least common. Switch between Characters and Words mode, toggle case sensitivity to merge or separate 'A' and 'a', and hide whitespace to keep the table focused on visible tokens. Each row shows the raw count and its share of the total as a percentage bar, so you can spot the dominant letters in a passphrase, the most repeated words in a paragraph, or unusual patterns in a cipher at a glance. It is useful for writers checking word repetition, students studying letter distributions, puzzle solvers analyzing substitution ciphers, and developers sanity-checking generated text. Everything runs locally in your browser, so nothing you paste is uploaded.
Features
Counts individual characters or whole words, switchable with one click
Sorts every token by frequency, highest count first
Shows a percentage share and a visual bar for each token
Case-sensitive toggle to merge or separate uppercase and lowercase letters
Ignore-whitespace toggle to hide spaces, tabs, and newlines from the table
Word mode strips surrounding punctuation so 'word,' and 'word' count together
Copy the full frequency table as tab-separated token and count pairs
Runs entirely in your browser with nothing uploaded
How to use the Character Frequency Counter
Paste or type text into the input box
Choose Characters or Words mode
Toggle case sensitivity or ignore whitespace as needed
Read the sorted frequency table and copy it if you need the raw numbers
Example
Input
mississippi
Output
i × 4 (36.36%)
s × 4 (36.36%)
p × 2 (18.18%)
m × 1 (9.09%)
Each letter's count and share of the 11 total characters, sorted highest first.
Common errors & troubleshooting
Uppercase and lowercase letters show up as separate rows. — Turn on the Case sensitive toggle only if you want that distinction; leave it off to merge 'A' and 'a' into one count.
The table is cluttered with a huge space row at the top. — Enable Ignore whitespace so spaces, tabs, and newlines are excluded from the character count.
Word mode counts 'word.' and 'word' as different tokens. — Word mode strips leading and trailing punctuation automatically, so check for stray internal punctuation or mixed casing if counts still look split.
Percentages don't add up to exactly 100%. — Each percentage is rounded to two decimal places for display, so small rounding differences across many rows are expected.
Frequently asked questions
What does the Character Frequency Counter measure?
It counts how many times each character (or, in Word mode, each word) appears in the text you paste, then sorts the results from most to least frequent with a percentage share for each one.
Does the Character Frequency Counter tell letters apart by case?
By default no — 'A' and 'a' are merged into one count. Turn on the Case sensitive toggle if you want uppercase and lowercase letters counted separately.
Can I count words instead of individual characters?
Yes. Switch to Words mode and the tool splits on whitespace, strips surrounding punctuation, and shows how many times each word occurs, sorted by frequency.
How do spaces, tabs, and newlines appear in the results?
In Character mode they show as labeled rows like (space), (tab), and (newline) so you can see them clearly. Enable Ignore whitespace to drop them from the table entirely.
Can I export the frequency table?
Yes. The copy button builds a tab-separated list of token and count pairs so you can paste the results straight into a spreadsheet.
Is the text I analyze uploaded anywhere?
No. The Character Frequency Counter runs entirely in your browser. The text you paste is analyzed on your device and never sent to ArrayKit.
