What Line Counter does
Line Counter turns one pasted or typed block into a clear measurement. It shows total lines, non-empty lines, blank lines, words, characters, characters without spaces, the longest line, and the detected line ending.
The live result is designed for quick decisions: check a text limit, review a code block, understand blank-line spacing, or prepare a line-by-line CSV report without opening a full editor.
Made for everyday text
The tool treats your input as text rather than trying to interpret its syntax. That keeps the result predictable across writing, code, data, and pasted output.
- Source code and configuration files
- Essays, drafts, subtitles, and notes
- CSV, JSON, Markdown, and log excerpts
- Support messages, terminal output, and form limits
Local by design
The normal counting workflow runs in the current browser tab. Pasted text stays in the page, and supported files are read through the browser File API rather than uploaded for counting.
Local processing is a practical design choice, not a universal security guarantee. Shared devices, browser extensions, clipboard history, and screenshots remain outside the page's control.
A small tool with clear rules
Line Counter explains how blank rows, whitespace-only rows, final newlines, and different line endings affect the result. The goal is a number you can understand and reproduce, not a mysterious score.
