Are my database queries sent to a backend server?

No. All SQL parsing, tokenization, formatting, and minification execute 100% locally inside your web browser. No network requests are made.

Can this tool minify SQL queries for production use?

Yes. Click the Minify button to strip single-line comments (--), block comments (/* */), and collapse extraneous whitespace while preserving string literals.

What happens if my SQL query has invalid syntax?

The tool preserves your raw input untouched and displays an informative error banner without crashing or losing your work.
