Using Sort Lines on really large documents

Most texts you work with don't justify opening Word. Sort Lines is for the in-between cases — paste, transform, paste back. Browser-local, no signup, no character limits.

Run it in your browser: Sort Lines — Free, no account required, no watermark.

Handling big text

Sort Lines handles documents up to several MB of plain text comfortably. Above that, the browser stops being the right shape — drop to a desktop editor. For most use cases (essays, articles, drafts, scripts), you're well within Sort Lines's working range.

Frequently asked questions

Can I trust the count for assignment / SEO purposes?

Sort Lines matches the published Unicode standard. Cross-check against the tool of record (Word, your CMS) if that's what's being graded against.

Will Sort Lines work offline?

Yes — once the page loads, processing happens locally with no further network calls.

Is there a length limit?

Practically, several MB of text. Beyond that the browser starts to lag.

Does Sort Lines count characters with or without spaces?

Sort Lines shows both counts simultaneously, so you can use whichever your target requires.
