Frequently Asked Questions
What does the SQL minifier remove?
It strips line comments (`-- comment`), block comments (`/* comment */`), and collapses multiple spaces and newlines into a compact single query string.
Can I use minified SQL in application connection strings or ORM configs?
Yes. Minified single-line SQL is ideal for embedding inside environment variables and inline configuration files.
Is my database schema or query uploaded to a server?
No. All SQL minification happens 100% locally in your browser memory.
How do I format minified SQL back into multi-line readable queries?
Use our SQL Formatter & Beautifier to restore indentation and dialect-specific formatting.
Does it work with MySQL, PostgreSQL, and SQLite?
Yes. Standard SQL queries from all relational databases are supported.
