Will it remove comment-like text inside strings?

No, string literals are tracked and left untouched.

Which languages are supported?

C-like languages (JS/TS/Java/C/CSS), HTML/XML, Python/shell (#), and SQL.

Are blank lines removed too?

Yes, lines that become empty after stripping comments are removed.

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.
