Best Free Word Counters Online

A comparison of the leading free online word counters — accuracy, readability scores, privacy, and ease of use.

What to look for in a word counter

  • Live updates — counts that refresh as you type, not after you click a button.
  • Six counts — words, characters with spaces, characters without, sentences, paragraphs, syllables.
  • Readability scores — at least Flesch Reading Ease + Flesch–Kincaid Grade Level.
  • Privacy — text should run in your browser, not be uploaded to a server.
  • No signup wall — the best counters work instantly without an account.
  • Mobile-friendly — readable layout on phone screens.

How to choose

For most writers, the right word counter is the one that fits your workflow:

  • For SEO writing: a counter with keyword density built in.
  • For academic essays: a counter that matches Microsoft Word's tokenisation exactly.
  • For social media: a character counter with platform-limit references.
  • For poetry: a counter with syllable counting and per-line breakdown.
  • For embedding on your site: a counter that offers an iframe widget — see our /widgets page.

Why we built Word Count Tool

Most free online word counters are slow, ad-heavy, missing readability scores, or upload your text to a server. We built Word Count Tool to do the opposite: lightweight, browser-only, six readability formulas, keyword density, and an embeddable widget.

What Word Count Tool offers that most don't

  • Six readability scores live as you type (most counters show one or none).
  • Reading and speaking time at common rates (250 WPM read, 130 WPM speech).
  • Browser-only privacy — text never leaves your device.
  • Free REST API — POST text, get JSON.
  • Embeddable widget — drop it into any website with a single iframe snippet.
  • 13+ related calculators — words to pages, words to minutes, syllable counter, sentence counter, paragraph counter, word frequency, and more.

Privacy comparison: cloud-based vs browser-only

Cloud-based counters upload your text to compute the count and return the result. Browser-only counters do all the math in your browser — your text never touches a network. For confidential drafts, browser-only is the only acceptable choice. Word Count Tool is browser-only.

Frequently asked questions

Are free word counters as accurate as Microsoft Word?

Is it safe to paste sensitive text into a free word counter?
Only if the counter is browser-only. Cloud-based counters upload your text. Our counter runs entirely in your browser — open developer tools and watch the network panel; no requests are made when you type.
What's the most-used free word counter?
wordcounter.net and our Word Count Tool are among the most-used. Both offer live counts and readability; we add reading time, keyword density, and an embeddable widget.
Is there a word counter API?
Yes — our free analyze API accepts a POST with the text and returns counts plus six readability scores in JSON. Free for non-commercial use.

Browser-only counters with responsive layouts work fine on mobile. Our counter is mobile-tested; if you find a layout issue, the contact page is the place to report it.
