  • Minify: Strip -- and /*...*/ comments and collapse whitespace into single spaces.
  • Goal: Improve readability or reduce size without changing SQL meaning.

FAQ

How to minify SQL for Java/Python strings?

Switch to Minify mode. We remove comments/newlines and output a single-line SQL string ideal for embedding.

Does this support Snowflake or PostgreSQL dialects?

Yes. Choose the dialect to better match vendor-specific syntax and formatting conventions.

Is my data safe (local/privacy)?

Yes. Processing is local-only with no uploads or server storage.

Is it free? Any limits?

Itโ€™s free. For very large queries, consider formatting in sections for best performance.

Will minifying change SQL behavior?

Minifying removes only comments and whitespace, so semantics stay the same in standard SQL usage. Always review edge cases.
