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.
