Word & Character Counter

Count words, characters, sentences, lines and keyword frequency in real time.

Your text is processed locally and never leaves your device.

0 / 5,000,000
Words: 0 · Characters: 0 · Lines: 0 · Bytes: 0

Text measurement explained

Use counts as diagnostics, not as a substitute for editing

The counter separates words with the browser's locale-aware text segmenter when available and also reports code units, user-perceived characters, bytes, lines, paragraphs and term frequency. Those measurements answer different questions and should not be treated as interchangeable.

Worked example: verify a short interface message

Analyze: “Clear writing helps readers find the answer and act with confidence.”

Inputs and process

  1. 1Locale: English
  2. 2Keep spaces and punctuation in the character total
  3. 3Compare characters, characters without spaces and UTF-8 bytes
  4. 4Review frequency only after checking the message itself

Result

The sentence contains 11 words, 68 JavaScript characters, 58 characters without whitespace and 68 UTF-8 bytes.

The word count describes segmentation, not clarity. The sentence succeeds only if its wording, purpose and context are useful to the reader.

Why the totals can differ

A visible character can be represented by more than one Unicode code point, and a code point can occupy multiple UTF-8 bytes. Emoji, combining marks and accented text are common reasons for character, grapheme and byte totals to diverge.

Word boundaries also depend on language and punctuation. Hyphenated terms, apostrophes and scripts without spaces may be counted differently by simplistic whitespace-based tools, which is why this page uses Intl.Segmenter when the browser provides it.

Real use cases

Interface constraints

Check labels, descriptions and messages against a documented product limit.

Editorial review

Find unusually long passages or repeated terms before reading the text for meaning and flow.

Encoding checks

Compare visible characters with UTF-8 bytes before storing or transmitting constrained data.
