SQL Pretty Print & Syntax Highlighting

Format SQL with colored syntax, then export as PNG or SVG for documentation, presentations, and code reviews.

What is SQL Pretty Print?

SQL pretty printing formats a query with consistent indentation and colors every element by type — keywords, functions, string literals, numbers, comments, and operators — so the query reads like well-structured code. This tool goes one step further than a plain formatter: it renders the highlighted output and exports it as a PNG or SVG image. That makes it ideal for documentation, slide decks, blog posts, and code reviews where a crisp, syntax-highlighted screenshot beats a plain-text code block. You can switch between dark and light themes to match your destination, and because rendering happens entirely in the browser, your SQL never touches a server. The result is not just well-formatted SQL — it is a presentation-ready asset you can drop into any document without reformatting.

How to Use the Pretty Printer

  1. Paste your SQL into the input panel (a sample query is pre-filled to get you started).
  2. Choose your database dialect from the dropdown so the formatter applies the right rules.
  3. Pick a Dark or Light theme.
  4. Click Format & Highlight to see the color-coded result, with a stats bar showing line and character counts.
  5. Click Export PNG or Export SVG to download the highlighted SQL as an image, or Copy to grab the plain formatted text.

Common Use Cases

Example

A dense single-line query is reformatted clause-by-clause with color-coded keywords, functions, strings, and numbers.

-- Input: SELECT u.name, COUNT(o.id) AS order_count FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE o.created_at >= '2025-01-01' GROUP BY u.name HAVING COUNT(o.id) > 5 ORDER BY order_count DESC; -- Formatted and highlighted output (one clause per line): SELECT u.name, COUNT(o.id) AS order_count FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE o.created_at >= '2025-01-01' GROUP BY u.name HAVING COUNT(o.id) > 5 ORDER BY order_count DESC;

Tips

SVG is resolution-independent, so prefer it for documentation and print; use PNG when you need a quick raster image for chat or a ticket. Before exporting, switch themes to match the destination — light for white-background docs, dark for slides and developer blogs. The formatter uses your selected dialect, so pick the right one to get correct handling of dialect-specific constructs. If the parser can't format a query, it still renders the raw text with syntax highlighting, so you always get a usable image. For very long queries, format first, then export in sections so the text stays legible at a readable font size. Note that Copy captures the plain SQL text, not the colors — the highlighting only appears in the rendered panel and in the exported PNG or SVG images.

Frequently Asked Questions

How do I export formatted SQL as an image?

Enter your SQL query, select your database dialect, click Format, then choose Export PNG or Export SVG. The syntax-highlighted output is rendered as a downloadable image file. Choose between dark and light themes before exporting. All processing happens client-side in your browser.

Can I use the SQL pretty printer for documentation screenshots?

Yes. The pretty printer is designed specifically for creating documentation-ready SQL images. Format your query with full syntax highlighting, choose your preferred color theme, and export as PNG or SVG. SVG exports are resolution-independent, perfect for inserting into technical documentation, wikis, and presentations.

What syntax highlighting does the SQL pretty printer support?

The tool highlights SQL keywords (SELECT, FROM, WHERE, JOIN, etc.), string literals, numbers, comments (both single-line -- and multi-line /* */), operators, and functions. The highlighting is based on tokenized analysis of the formatted output, producing accurate and readable color-coded SQL for any dialect.

Is the SQL pretty print tool free with no limits?

Yes. Completely free with no signup, no limits, and no data sent to servers. Everything runs in your browser. You can format and export as many SQL queries as you need. The PNG and SVG exports have no size restrictions.
