How to Count Word Frequency in Any Text (Free Tool)

To count word frequency in any text, paste it into the ByteTools Word Frequency Counter and it instantly lists every word ranked from most to least common, with an exact count and a percentage for each. There is nothing to install and nothing to send to a server — the whole tally happens on your device the moment you paste.

Word frequency analysis answers a simple question: which words carry the most weight in a piece of writing? That single view is useful whether you are trimming an overused phrase from an essay, studying the vocabulary of a novel, or checking that a target keyword actually appears often enough on a page.

What the tool does

The counter splits your text into individual words, groups identical words together, and sorts the list so the most frequent term sits at the top. Each row of the results table shows three things: the word itself, how many times it appears, and what share of the total that count represents. Because percentages are calculated from the words that remain after filtering, they always add up to a picture of your real content rather than raw noise.

Two switches change how words are grouped. Ignore case merges words that differ only by capitalization, so "Data" and "data" become one entry instead of two. Ignore stop words hides high-frequency function words such as "the", "and", "of" and "is" so the meaningful terms rise to the surface.

Step-by-step: counting word frequency

1. Paste or type your text into the input box. A sentence, an article, or a whole chapter all work the same way.
2. Turn on "Ignore case" if you want capitalized and lowercase versions of a word counted as one. Leave it off when case genuinely matters, for example when tracking proper nouns.
3. Turn on "Ignore stop words" to strip out common filler and reveal the content words that define the text.
4. Read the ranked table. The word at the top is the one you use most; scan down for surprises and repetition.
5. Copy the results as a table to reuse the counts in a spreadsheet, a report, or your notes.

Reading the results table

Here is what a small result set looks like after case normalisation and stop-word filtering on a short marketing paragraph:

At a glance you can see the paragraph leans heavily on "browser" and "free". If that repetition is intentional emphasis, keep it; if it reads as monotonous, the table tells you exactly which words to vary.

Why an in-browser tool keeps your text private

Every step above runs in JavaScript inside your own browser tab. Your text is never uploaded, stored or logged, which matters when you are analysing an unpublished manuscript, a confidential report, or a client draft under NDA. The tool also works offline once loaded, so you can run an analysis on a plane or anywhere without a connection. Privacy here is not a promise about a server policy — the data simply never leaves your machine.

FAQ

How long can the text I paste be?

The tool is built to handle long documents smoothly, so full articles and multi-page chapters count without slowing down. Very large inputs may take a moment to render the table, but the calculation itself stays local and fast.

Do numbers and symbols get counted as words?

The counter focuses on words, splitting on whitespace and punctuation, so ordinary sentences produce a clean word list. Stray symbols are not treated as meaningful words, which keeps the ranking readable.

Should I turn on case normalisation for keyword research?

Usually yes. For keyword and vocabulary analysis you care about the word, not its capitalization, so merging "SEO" and "seo" into one entry gives a truer count. Leave case sensitivity on only when capitalization itself is the thing you are studying.

Can I use the counts in a spreadsheet?

Yes. Copy the results as a table and paste them into a spreadsheet to sort, chart, or compare word frequencies across several documents.
