Your SQL never leaves your browser. Nothing is uploaded.

Formatted SQL appears here…

Formatting is lenient — it pretty-prints what you paste rather than fully validating syntax. Minify collapses each statement to a compact single line. Changing any option above re-formats automatically.

Readable SQL, without a paste-into-a-website round trip

Messy SQL is hard to review and harder to trust. This formatter beautifies queries with consistent indentation and keyword casing so joins, filters and aggregates read at a glance — or minifies them to a single compact line when you need to inline a statement. It understands 13 dialects (MySQL, PostgreSQL, SQL Server, BigQuery, Snowflake, Redshift, SQLite, Spark, Trino, Db2, Oracle PL/SQL and Standard SQL), and the whole engine runs in your browser — paste production queries here without a single byte leaving your machine. No account, no upload, free forever.

§ 04 · faq

Frequently asked questions.

Is the SQL Formatter free?
Yes — completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Is my SQL uploaded anywhere?
No upload, ever. The formatter runs entirely in your browser on your own device — your queries never leave your computer, so it is safe to paste production SQL.
Does it work offline?
Yes — once the page has loaded, formatting and minifying keep working without a connection, because all logic runs locally.
Which SQL dialects are supported?
Thirteen: Standard SQL, MySQL, MariaDB, PostgreSQL, SQL Server (T-SQL), BigQuery, SQLite, Redshift, Snowflake, Spark, Trino / Presto, Db2 and Oracle PL/SQL.
Does it validate my SQL?
Not fully. Formatting is lenient — it pretty-prints what you paste for readability rather than checking that the query is valid. If the parser hits input it can't read, it flags an error instead of producing broken output.
What is the difference between Format and Minify?
Format beautifies the query across multiple lines with your chosen indent and keyword case for reading and review. Minify does the opposite — it collapses each statement to one compact line (preserving text inside quotes) and reports how many bytes you saved.
