About the SQL Minifier
Minify SQL by removing comments and unnecessary whitespace while keeping string literals intact — for embedding queries in code, logs and configuration.
Built for developers
Why developers use it
Private by design
Runs 100% in your browser. Nothing you paste is uploaded, logged or stored on a server.
Instant results
Output updates as you type, with precise error locations when something is wrong.
Works offline
Once loaded, the tool keeps working without a connection. Install it as an app if you like.
Free, no sign-up
No accounts, no limits, no watermarks.
FAQ
Frequently asked questions
Does my code leave my computer?
No. Formatting, minifying and validation run entirely in your browser with open-source engines, so proprietary code stays private.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you type, paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
