Compress a SQL query into a single compact line by stripping comments and unnecessary whitespace.
Your Data Never Leaves Your Device
Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The SQL Minifier is a free, client-side tool that compresses SQL queries by removing comments, extra whitespace, and line breaks — producing the most compact version of the same query.
Minifying is useful when embedding SQL in application code, sending it over an API, or reducing storage size. The query's logic stays identical — only the formatting is stripped. All processing happens locally in your browser—your queries never leave your device.

Minifying strips comments, collapses extra whitespace and line breaks, and removes unnecessary spacing around punctuation, producing the most compact version of the same query.

No. Minifying only removes formatting — comments and whitespace — it doesn't alter keywords, identifiers, or logic, so the query behaves exactly the same.
Yes, minification is whitespace-based and dialect-agnostic, so it works the same way for PostgreSQL, MySQL, BigQuery, SQLite, and other SQL dialects.
No, minification happens entirely in your browser. Your queries never leave your device.
Yes, see the SQL Query Formatter for beautifying SQL with custom indentation and keyword casing — the opposite of minifying.
