What the Line Counter does
Fast line counter for code, CSV files and lists. Shows total lines, non-empty lines and unique lines. The Line Counter is built for writers, students, editors, marketers and developers who need reliable statistics without opening a heavy word processor. It loads in under a second, works offline once loaded, and gives you the same answer every time.
Under the hood the tool applies careful text-parsing rules — Unicode-aware tokenisation, punctuation-sensitive sentence splitting, and blank-line paragraph detection — so it matches what a human editor would count. That accuracy matters when you're trying to hit a specific word count for a client brief, a submission guideline or an SEO target.
Why the Line Counter is useful
Because everything runs locally in your browser, you can paste sensitive material — legal drafts, client work, medical notes, confidential briefs — without worrying about a server logging it. There is no account, no upload, no processing queue and no tracking of the text you enter.
The Line Counter is designed to fit into a real writing workflow. Keep it open in a tab while you draft, glance at the counts as you edit, and copy the final numbers into your brief or CMS. Combined with the rest of the tools at Text Tools Hub — the Reading Time Calculator, Keyword Density Checker and Text Case Converter — it becomes a lightweight editor's toolkit that lives one bookmark away.
Also known as: line counter, count lines, free line counter, online line counter, line counter online free, line counter tool, best line counter tool.

Real-life use cases
Students and academics
Essay and dissertation briefs almost always carry a strict word range. Checking as you write stops the painful end-of-night edit where you have to cut 400 words from a finished argument.
Content writers and editors
Client briefs are priced per word, so accurate counts protect both sides. Editors also use the sentence and paragraph numbers to spot walls of text before a piece goes to layout.
Marketers and social teams
Ad headlines, meta descriptions, push notifications and X posts all have hard limits. Counting before you schedule avoids truncated copy that loses the call to action.
Tips for the best results
- Paste plain text rather than richly formatted content so hidden characters do not skew the totals.
- Separate paragraphs with a single blank line — that is how the paragraph count is detected.
- Compare the sentence and word counts to spot sentences that have grown too long for comfortable reading.
