About SQL Minifier
Sometimes you need SQL compact rather than pretty. Embedding a query in a config file, a single-line environment variable, or a log statement is far easier when it is collapsed to one line with comments and redundant whitespace stripped out. The SQL Minifier takes a formatted query and squeezes it down, removing line breaks, extra spaces, and inline comments while keeping the statement valid and executable.
Drop in your SQL and get a minified version back instantly, ready to paste wherever a tidy single line is required. The tool runs entirely in your browser, so there is no upload, no signup, and no watermark, and your query stays on your device. It is a quick way to shrink SQL for storage or transport without hand-editing every space and newline yourself.
Common uses
- Collapsing a query into a single line to store it in a JSON or YAML config value.
- Stripping comments from SQL before shipping it in application code.
- Reducing query size for log statements or audit trails where space is tight.
- Cleaning developer notes out of a query before handing it to another system.
- Packing a query into an environment variable that expects one line.

FAQ
Does minifying break my query?
No. It removes only whitespace and comments that the database ignores, so the statement still runs and returns the same results.
Are comments removed too?
Yes. Both inline and block comments are stripped since they only add size without affecting execution.
Can I reverse it later?
Minifying is one-way for whitespace, but you can paste the result into our SQL Beautifier to make it readable again.
Is my SQL sent to a server?
No. The whole process runs in your browser, so nothing about your query leaves your machine.
Can I use SQL Minifier on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
