Does this count characters or bytes?

It counts Unicode characters (code points), so accented letters, emoji, and CJK characters each count as one character, not by their byte length.

Are blank lines included in the sort?

Yes. Blank lines have a length of zero and sort to the top in ascending mode or the bottom in descending mode. You can remove them manually before sorting if you prefer.

Does sorting preserve ties?

Lines with equal lengths maintain their original relative order (stable sort), so the output is predictable.

Is my text sent to a server?

No. All processing happens entirely in your browser with JavaScript. Nothing is uploaded or stored.

What is the maximum number of lines I can sort?

There is no hard limit. The browser handles tens of thousands of lines without issues. Very large pastes (millions of lines) may slow down rendering, but there is no artificial cap.
