How to use SQL Minifier
- Paste or type your contentThe result appears as you type — there is no submit button.
- Read and copy the resultThe output updates live and the copy button takes it in one click.
Worked example
- SELECT * FROM users -- comment WHERE id = 1
- SELECT * FROM users WHERE id = 1
Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
SQL Minifier only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
