Tail — Last N Lines
Keep just the last N lines of your text — like `tail -n`. Choose the count, skip trailing lines, and optionally number each line. Runs entirely in your browser, no server, no sign-up.
About this tool
Tail keeps just the last lines of whatever text you paste — the same thing
the Unix tail -n command does, but in your browser with no install. Paste a
log, a CSV, a giant export, or any block of text and instantly get back only the
bottom rows.
What you can do
- Keep the last N lines. Set Number of lines to keep (default 10) to take exactly that many trailing lines.
- Skip a footer row. Use Skip trailing lines to drop lines from the very end before counting — for example skip 1 to ignore a totals or summary line.
- Number each line. Turn on Number each line to prefix every kept line with
its original 1-based line number and a tab, like
cat -nornl, so the numbers reflect each line's real position near the end of the input.
Windows line endings (CRLF) and a trailing newline are preserved, so the tail of a file keeps its original structure.
Private by design
Everything runs locally in your browser via WebAssembly. Your text is never uploaded to a server — there's nothing to sign up for and nothing leaves your machine.
FAQ
How do "skip" and "count" interact?
Skip is applied first: the last skip lines are dropped from the end, then the last count lines of what remains are kept. So count=10, skip=1 gives you rows 11-through-2 from the bottom — perfect for ignoring a totals/footer row.
What do the line numbers refer to when numbering is on?
Each kept line is prefixed with its 1-based position in the original text (plus a tab), not a fresh 1..N sequence. If your input had 500 lines and you keep the last 10, they're numbered 491-500, so you can locate them in the source file.
Is there a maximum line count?
Count is clamped to the range 1 to 1,000,000. Asking for more lines than the text contains simply returns the whole text — no error, same as tail -n on a short file.
Does it mangle Windows (CRLF) files or the trailing newline?
No — CRLF endings are preserved on each line, and a final newline is kept only if the original input ended with one, so the tail is byte-faithful to the source.
