SQL Minifier – Free Online SQL Compressor (No Execution)

1️⃣ What is SQL Minifier?

SQL Minifier is a free online utility that compresses bulky SQL code into a concise, single-line format. By removing line breaks, indentation, and comments, it reduces the size of your query strings.

It is specifically designed for developers needing to embed SQL in application code (like Java, Python, or PHP) or log queries efficiently without taking up vertical space.

2️⃣ When Should You Use This Tool?

• Embedding SQL in Code: Clean up your source code by turning multi-line strings into one-liners.
• Reducing Network Payload: Send smaller query strings over APIs or networks.
• Log Files: Log SQL queries on a single line to keep log files readable and compact.
• Copy-Pasting: Quickly share queries in chat apps (like Slack or Teams) without flooding the screen.

3️⃣ Example

SELECT 
    id, 
    email 
FROM users 
WHERE status = 'active'
-- Filter by date
AND created_at > '2024-01-01';

SELECT id, email FROM users WHERE status = 'active' AND created_at > '2024-01-01';
