Examples
Input
SELECT users.name, users.email, orders.total FROM users INNER JOIN orders ON users.id = orders.user_id WHERE orders.total > 100 ORDER BY orders.total DESC LIMIT 10;
Output
SELECT users.name,users.email,orders.total FROM users INNER JOIN orders ON users.id=orders.user_id WHERE orders.total>100 ORDER BY orders.total DESC LIMIT 10;
Input
INSERT INTO products ( name, price, category, in_stock ) VALUES ( 'Widget Pro', 29.99, 'Electronics', true );
Output
INSERT INTO products(name,price,category,in_stock)VALUES('Widget Pro',29.99,'Electronics',true);What Is SQL Minification?
SQL minification compresses formatted SQL queries into compact, single-line statements by removing unnecessary whitespace, line breaks, and extra spaces around operators. The resulting query is functionally identical to the original — the database engine interprets both versions the same way.
Minified SQL is commonly used when embedding queries in application code, configuration files, or logging systems where readability is less important than compactness. It is also useful for reducing the size of SQL payloads sent over network connections or stored in version-controlled migration files.
This tool is smart about preserving string literals. Quoted values like 'Hello World' keep their internal spacing intact, ensuring the minification never corrupts your data. Spaces around SQL operators (=, >, <) and parentheses are removed where safe, but the semantic meaning of every clause is preserved.
For development, you typically want formatted SQL for readability. For production logs, embedded queries, and compact storage, minified SQL is the better choice. Many teams use a formatter during development and a minifier in their deployment pipeline to get the best of both worlds.
Everything runs in your browser. Your SQL queries — whether they reference internal table schemas, sensitive column names, or proprietary database structures — are never sent to any server. The minification happens instantly on your device.
