Can I remove all blank lines?

Yes, toggle 'Remove all blank lines' to strip every empty line entirely.

What's the difference between removing and collapsing blank lines?

Collapsing reduces consecutive blank lines to one; removing deletes all blank lines.

Can I convert tabs to spaces?

Yes, choose a tab/space conversion mode from the dropdown.

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.
