SQL Minifier
Minify SQL queries by stripping comments and collapsing whitespace to reduce file size, with before/after character counts.

How Does It Work?
The SQL Minifier strips unnecessary whitespace from your SQL queries to reduce their size. It collapses multiple spaces into one, removes line comments (-- style) and block comments, trims whitespace around commas, parentheses, semicolons, and equals signs, all while preserving the query's logic and behavior.
Example
Input: SELECT id, name
FROM users
WHERE active = 1;
Minified: SELECT id, name FROM users WHERE active = 1;
Common Use Cases
- Reducing SQL query size for embedding in application code or configuration files.
- Cleaning up auto-generated or ORM output queries for readability in logs.
- Minimizing network payload size when sending queries to databases over slow connections.
- Preparing SQL for inclusion in JSON or YAML configuration files where whitespace matters.
FAQs
Will minifying change how my query runs?
No. Removing comments and extra whitespace does not affect SQL execution. The database parser treats minified SQL identically to formatted SQL.
Does it handle multi-line comments?
Yes — both single-line comments (-- style) and block comments (/* ... */) are removed by the minifier.
What about string literals containing spaces?
The minifier does not parse string literals, so spaces inside quoted strings may be collapsed. For production use with complex SQL, a dedicated SQL parser is recommended.
