Free Online SQL Pretty Printer — Syntax Highlighting & Image Export
SQL pretty printing is the practice of formatting raw SQL queries with proper indentation, line breaks, and color-coded syntax highlighting. A SQL pretty printer transforms messy, hard-to-read queries into clean, visually organized code that is easy to understand, review, and share. The free online SQL pretty printer at SQLFormat.io goes a step further — it lets you export formatted SQL as PNG or SVG images, making it the perfect tool for documentation, presentations, and code reviews.
Open SQL Pretty Print →When you paste a SQL query into the pretty printer, it applies intelligent formatting that respects your database dialect's syntax rules. Keywords become one color, string literals another, and numbers, comments, and operators each get their own distinct hue. The result is not just formatted — it's visually parseable at a glance.
Why Use a SQL Pretty Printer with Image Export?
Documentation Ready
Export formatted SQL as clean SVG or PNG images that are ready to insert into technical documentation, wikis, and developer guides. SVG exports are resolution-independent and look sharp at any size.
Presentations & Slides
Create professional SQL code images for PowerPoint, Keynote, or Google Slides presentations. Choose the light theme for printed handouts or the dark theme for screen presentations.
Code Reviews
Share formatted and highlighted SQL snippets in code review comments. The syntax highlighting makes it easy for reviewers to spot keywords, table names, and conditions at a glance.
Social Media & Blogging
Post attractive SQL code screenshots on Twitter, LinkedIn, or Dev.to. A well-formatted, color-highlighted SQL image gets more engagement than a code block.
Syntax Highlighting: Every Token Gets Its Color
The free online SQL pretty printer tokenizes your formatted SQL and assigns a distinct color to each type of token:
- Keywords (
SELECT,FROM,WHERE,JOIN,GROUP BY, etc.) — rendered in a distinct red/pink tone in both dark and light themes - Functions (
COUNT(),SUM(),COALESCE(),ROW_NUMBER(), etc.) — purple/violet coloring for immediate recognition - String literals — blue tones to distinguish data values from structure
- Numbers — bright blue for easy spotting in queries with LIMIT, OFFSET, or WHERE clauses
- Comments (
-- single line,/* block */) — italic and muted gray to de-emphasize notes - Operators (
AND,OR,IN,BETWEEN,LIKE) — orange/amber to highlight logical connections
Choose between Dark Theme (GitHub-style dark background, ideal for developer screens and modern docs) and Light Theme (white background, perfect for print, publications, and formal documentation).
Export Formats: PNG vs SVG
The SQL pretty printer supports two export formats, each suited to different use cases:
- PNG Export — Raster image format, good for social media, screenshots, and embedding in documents where a fixed-resolution image is fine. The SQL is rendered onto an HTML5 Canvas element with exact pixel positioning.
- SVG Export — Vector image format, best for professional documentation, print, and any use case requiring resolution independence. SVG images scale perfectly to any size without quality loss. Each character is an individual text element with its own color, producing crisp output at any zoom level.
15+ SQL Dialects Supported
The SQL pretty printer works with all major database dialects, ensuring accurate formatting and highlighting regardless of your database platform: MySQL, PostgreSQL, SQLite, BigQuery, DB2, Hive, MariaDB, PL/SQL (Oracle), Redshift, SingleStoreDB, Snowflake, Spark SQL, T-SQL (SQL Server), Trino, and Standard SQL.
Privacy & Security
Like all tools on SQLFormat.io, the SQL pretty printer runs entirely in your browser. There are no server requests, no data storage, and no logging. Your SQL queries and formatted output never leave your device. This makes it safe to use with proprietary queries, production SQL, and sensitive database schemas.
