GeoJSON to PNG Converter

Convert GeoJSON to PNG (Portable Network Graphics) raster images with transparency support. Perfect for presentations, web overlays, and print materials.

Why PNG?

Transparency Support

• Alpha channel — Smooth anti-aliased edges
• Transparent backgrounds — Overlay on other graphics
• No white borders — Clean integration with designs
• Layer compositions — Stack multiple maps

Lossless Quality

• No compression artifacts — Unlike JPEG
• Crisp lines — Sharp boundaries and strokes
• Color accuracy — Preserves exact colors
• Professional quality — Suitable for print

Universal Compatibility

• Every device — Desktop, mobile, tablets
• All software — PowerPoint, Photoshop, Word, etc.
• Web-ready — <img> tags, CSS backgrounds
• Email-safe — Embed in email signatures

Use Cases

✅ Presentations — PowerPoint, Keynote, Google Slides ✅ Documents — Word, PDF, reports ✅ Web overlays — Layer over photos or videos ✅ Print materials — Flyers, posters, brochures ✅ Social media — Graphics with transparent maps ✅ Photo editing — Combine with photos in Photoshop

How to Convert

1. Upload your GeoJSON file (drag-and-drop or browse)
2. Select PNG format from the dropdown
3. Set width (height scales automatically to maintain aspect ratio)
4. Preview the map rendering
5. Download your PNG image

The tool generates high-quality PNG images with transparent backgrounds by default.

Tips for Best Results

Choosing the Right Width

• Web use: 800-1200px (fast loading)
• Presentations: 1200-1600px (HD screens)
• Print: 2000-4000px (300 DPI at 6-13 inches)
• Social media: 1080px (Instagram), 1200px (Twitter)

File Size Optimization

• Lower width — Smaller file size
• Simplify geometry — Fewer coordinates = smaller image
• Solid colors — Reduces PNG complexity
• Avoid gradients — Creates larger files

Quality Tips

• Start larger — Easier to scale down than up
• Test at final size — Verify quality at intended use size
• Check transparency — View against dark/light backgrounds
• Preview before download — Verify rendering

Design Considerations

• White vs transparent — Choose based on background
• Stroke visibility — Thicker strokes for smaller sizes
• Label readability — Add labels in design software after export
• Color contrast — Ensure visibility on target background

Technical Details

Format Specifications

• Format: PNG-8 or PNG-24 (24-bit RGB + 8-bit alpha)
• Compression: Lossless (no quality loss)
• Transparency: Full alpha channel support
• Color depth: Millions of colors

Resolution

• DPI: Depends on width and display size
• Web: 72-96 DPI standard
• Print: Calculate: (pixel width) / (inches) = DPI
  • Example: 3000px ÷ 10 inches = 300 DPI (print quality)

File Size

• Varies by width and complexity
• Example sizes:
  • 800px simple map: 20-50 KB
  • 1200px complex map: 100-200 KB
  • 2000px detailed map: 300-500 KB
  • 4000px high-res: 800 KB - 2 MB

Browser Compatibility

• ✅ 100% universal support
• ✅ All browsers, all devices
• ✅ Transparent backgrounds work everywhere

FAQs

What width should I use? For web use, 800-1200px is ideal. For print, use 2000px+ to ensure 300 DPI at your final print size.

Does PNG support transparency? Yes! PNG has full alpha channel support with smooth anti-aliased edges.

Can I use PNG for print? Yes, but use a high width (2000-4000px) to ensure sufficient resolution for print quality.

How do I change the background color? PNG exports with transparent backgrounds by default. To add a background, open in an image editor (Photoshop, GIMP) and add a layer beneath.

Why is my file so large? Large widths and complex maps create bigger files. Reduce width or simplify your GeoJSON geometry to decrease file size.

Can I edit PNG after export? PNG is a raster format, so you can edit pixels in image editors (Photoshop, GIMP) but can't edit vector paths like SVG.

PNG vs JPEG? Use PNG for transparency and sharp lines. Use JPEG for smaller file sizes when transparency isn't needed.

PNG vs SVG? Use SVG for infinite scalability and editability. Use PNG for fixed-size images with transparency in non-vector software.
