What is SQL Minifier?

Click Minify.
Copy the compressed result from the Output box.

Frequently Asked Questions

Does this execute my SQL?

No. This tool only rewrites the text of your query. It never connects to a database or executes anything.

Are comments removed?

Yes. Both -- line comments and /* block comments */ are stripped, since they aren't needed once the query is minified.

Is my SQL uploaded to a server?

No. Minifying happens entirely in your browser.

Will minifying change what my query does?

No. Only whitespace and comments are removed — every identifier, literal and operator is preserved exactly.
