Free SQL Minifier

Compress SQL to a single clean line for logging, embedding, or transport. This free minifier strips comments and collapses whitespace — while protecting string literals so your quoted values survive intact.

Features

    
The minifier is string-aware: single- and double-quoted literals (including escaped quotes) pass through untouched while -- line comments and /* block */ comments are removed. Whitespace runs collapse to single spaces with protection around the characters that need it, producing a safe one-line query.

    
Benefits & Use Cases

    
Developers compress queries for compact logging and error reports; anyone embedding SQL in JSON payloads, code strings, or URLs needs the single-line form; teams strip explanatory comments before sharing queries externally. Local processing keeps query contents private.

    
Tips

    
Keep the readable original — minified SQL is for transport, not for editing. Double-check that no comment contained a hint your query relied on (like optimizer hints) before stripping.

  

  

    
Frequently Asked Questions

    
What does SQL minification do?
It removes comments and collapses all unnecessary whitespace, producing the shortest single-line form of the query. The logic is unchanged — only formatting is stripped.

    
Is the minified query still valid?
Yes. String literals are protected during minification and only insignificant whitespace is removed, so the query executes identically.

    
Should I remove comments?
For logging and sharing externally, usually yes. But keep optimizer hints and important notes in your source file — minify a copy, not the original.

    
Does minification make queries run faster?
No — the database parses both forms the same way. Minification saves space in logs, code, and transit, not execution time.

    
Is my SQL uploaded anywhere?
No. Minification runs entirely in your browser — your queries never leave your device.
