Frequently Asked Questions

What does SQL Minification do?

SQL Minification removes all unnecessary whitespace, newlines, and comments from a SQL query, producing a compact single-line version that is functionally identical but smaller in character count.

Does it remove SQL comments?

Yes. Both single-line comments (-- comment) and multi-line comments (/* comment */) are removed during minification.

When would I minify SQL?

Common use cases: embedding SQL in environment variables or config files where multiline strings are difficult, including SQL in JSON config, storing queries in database tables as single strings, or reducing payload size in API requests that include raw SQL.

Does minified SQL still work correctly?

Yes. SQL minification only removes whitespace and comments — the query structure and logic remain identical. Databases parse minified SQL exactly the same as formatted SQL.

Can I download the minified SQL?

Yes. Click the ⬇ Save .sql button or press Ctrl+S to download the minified SQL as a .sql file.
