Frequently asked questions
Is SQL Formatter free to use?
Yes. SQL Formatter is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does SQL Formatter upload your file to a server?
No. SQL Formatter processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in SQL Formatter.
Do I need to install anything to use SQL Formatter?
No installation is needed. SQL Formatter runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use SQL Formatter on a phone or tablet?
Yes. The SQL Formatter interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. SQL Formatter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
