Can I start numbering from a value other than 1?

Yes, set any starting number in the options bar.

What separators are supported?

Any text you like, such as '. ', ') ', or a tab character.

How does removing line numbers work?

It strips a leading number followed by an optional punctuation mark from each line.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
