SQL Query Minifier & Single-Line Optimizer

Minify SQL queries by removing comments, collapsing whitespace, and compressing queries for embedded application strings.

Input SQL Query:

Minified Single-Line SQL:-28% size reduction (281 ➔ 201 chars)

SELECT u.id, u.email, COUNT(o.id) AS total_orders FROM users u LEFT JOIN orders o ON o.user_id = u.id WHERE u.status = 'active' GROUP BY u.id, u.email HAVING COUNT(o.id) > 5 ORDER BY total_orders DESC;

About This Tool

The SQL Query Minifier strips inline comments (`--`), block comments (`/* ... */`), collapses multi-line formatting into single-line queries, and optimizes database query payload size.

Key Features

Strips single-line (`--`) and multi-line (`/* */`) comments

Collapses whitespace and indentation into a single compact line

Preserves string literals enclosed in quotes

Calculates payload size compression percentage

How to Use This Tool

Paste your formatted SQL query into the input box.
Instantly view the minified single-line SQL query.
Copy the compressed SQL string for use in code constants.

Why Use This Tool

Embed clean SQL queries into Go, Python, or JavaScript string constants without awkward linebreaks.
Reduce network payload size when submitting queries over HTTP database endpoints.

Pro Tips

The minifier protects strings enclosed in single and double quotes.

Frequently Asked Questions

Does minifying SQL change query execution speed inside the database?

Query execution speed is identical because database query planners parse SQL into an abstract syntax tree. However, minification reduces file size and network transmission bandwidth.

Will comments inside SQL strings be removed?

No, our parser protects text inside quoted string literals (e.g. `'-- not a comment'`).
