SQL Minifier

Compress and minify your SQL queries. Remove comments, newlines, and unnecessary whitespace to reduce size.

Optimize Your Queries

Large SQL scripts with comments and formatting are great for humans but unnecessary for databases. our SQL Minifier strips away the bloat, condensing your queries into efficient, compact strings.

Shrink Your SQL Queries for Production

Well-formatted SQL is essential during development, but all that whitespace and those comments add overhead when queries are transmitted over a network or embedded in application code. Our SQL Minifier strips comments, collapses whitespace, and tightens operators to produce the smallest valid query string possible.

Reduce Query Size

Why Use This Tool?

Removes Both Comment Types

Strips single-line (--) and multi-line (/* */) comments in one pass, eliminating the documentation overhead that accumulates in complex stored procedures and migration scripts.

Dialect-Agnostic

Works with MySQL, PostgreSQL, SQL Server, SQLite, and Oracle syntax. The minification targets universal SQL constructs — whitespace and comments — without touching dialect-specific keywords.

File Upload Support

Upload a .sql file directly instead of pasting large scripts manually. The minified output is ready to copy back into your project without leaving the browser.

Instant Live Output

Minification runs automatically as you type, so the compressed output is always up to date. No need to click a button — paste and copy in under a second.

How this SQL Minifier works

This code beautifier organizes messy SQL queries into structured, readable code. It adds proper indentation, line breaks, and capitalization to keywords (SELECT, FROM, WHERE). It supports various SQL dialects (MySQL, PostgreSQL, SQL Server). Essential for developers debugging complex queries or reviewing legacy code. The formatter runs locally, ensuring that sensitive database queries and schema structures are never transmitted to an external server.

Need compact SQL for deployment scripts? Our SQL Minifier does the reverse.

Frequently Asked Questions

Why minify SQL?

Minifying reduces the size of query strings, which can save bandwidth when transmitting queries over networks or storing large scripts.

Does it remove comments?

Yes, both single-line (--) and multi-line (/* */) comments are stripped out.

Is it safe for all SQL dialects?

The minification logic is generic and works with standard SQL (MySQL, PostgreSQL, SQL Server, etc.). It mainly targets whitespace and comments.
