Count total lines, non-empty lines, and blank lines in any text instantly
A line counter is a simple but essential tool that counts the number of lines in a block of text. It provides three key metrics: total lines (every line including blanks), non-empty lines (lines that contain at least one character), and blank lines (lines with no content at all). This breakdown gives you a much clearer picture of your text structure than a simple total line count.
Our free online line counter processes everything locally in your browser. There's no server upload, no data storage, and no privacy concerns — your text stays on your device at all times. Just paste your text and see the line statistics instantly.
Using the line counter is straightforward:
Code and log file analysis: Developers frequently need to count lines in code files, log outputs, or configuration files. The non-empty line count is especially useful for measuring actual code content versus blank lines that serve as formatting.
Writing and editing: Writers use line counters to measure the length of poetry, scripts, or formatted text where line count matters more than word count. Screenwriters, poets, and lyricists all benefit from precise line counting.
Data processing: When working with CSV exports, database dumps, or scraped data, knowing the number of lines helps you understand dataset size and detect formatting issues like extra blank lines at the end of files.
Academic and administrative: Researchers counting survey responses, administrators processing form submissions, and students checking document formatting all rely on line counting for accuracy and consistency.
Unlike many online line counters that send your data to remote servers, our tool is 100% client-side. This means your text is never transmitted, stored, or accessible to anyone else. The tool is also completely free with no usage limits, no account required, and no ads interrupting your workflow. It works offline too — once the page loads, you can disconnect from the internet and it continues to function perfectly.
