Minify SQL queries to single line. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.
A SQL Minifier collapses a well-formatted, multi-line query into a single compact line by removing indentation, extra line breaks, and redundant whitespace around keywords and punctuation. It's the inverse of a SQL formatter: instead of optimizing for a human reading the query, it optimizes for a context where the query needs to be as short as possible — embedded in a shell one-liner, stored as a single-line value in a config file, or pasted into a tool that doesn't handle multi-line input well. The tool preserves the exact clause order, identifiers, and literal values while stripping only the whitespace that has no effect on execution.
Some environments genuinely need SQL on a single line — a database migration tool that stores queries as one-line JSON values, a shell script that passes a query as a command-line argument, or a config file format that doesn't support multi-line strings gracefully. Rather than manually deleting every line break and extra space by hand (and risking a typo that breaks the query), minifying does it in one click while guaranteeing the query's logic is untouched.
No, only whitespace is removed. Keywords, identifiers, literal values, and clause order remain exactly as in the original query, so it executes identically.
No, text inside string literals (e.g. 'John Doe') is preserved exactly — the minifier only strips whitespace that sits outside of literal values.
Line comments (--) and block comments (/* */) are handled carefully so minifying doesn't accidentally merge a comment with the next line of code.
Yes, each statement is minified while the semicolon separators and overall statement order are kept intact.
No, the entire process runs in your browser using JavaScript.
