Frequently asked questions
Is SQL Minifier safe to use on production code?+
It's a conservative, structure-preserving tool that won't corrupt string or template literals. For maximum compression in a real pipeline, pair it with a dedicated bundler — this is perfect for quick, ad-hoc trimming.
Will minifying change how my code behaves?+
No. SQL Minifier only removes comments and redundant whitespace; the meaning of the document stays identical. Output simply transfers and parses faster.
Is SQL Minifier free?+
Yes. SQL Minifier is completely free with no sign-up, no account, no usage limits and no watermarks. Use it as often as you like.
Does SQL Minifier send my data to a server?+
No. SQL Minifier runs entirely in your browser with JavaScript — your input never leaves your device, which makes it safe for private API payloads, schemas and source code.
