Why JPEG?

Smallest File Sizes

  • Highly compressed — 5-10× smaller than PNG
  • Fast loading — Ideal for web galleries
  • Bandwidth-friendly — Mobile-optimized
  • Email-friendly — Quick attachments

Universal Support

  • Every device — Desktop, mobile, tablets
  • All software — Office, email, browsers
  • Social media — Optimized for Facebook, Instagram, Twitter
  • Backwards compatible — Works on old systems

Photo Compression

  • Optimized for images — Designed for photos and graphics
  • Quality control — 92% quality balance for maps
  • Efficient encoding — Reduces file size intelligently
  • Web standard — Most common image format online

Use Cases

Web galleries — Fast-loading map collections ✅ Email attachments — Quick to send and receive ✅ Social media — Instagram, Facebook, Twitter posts ✅ Blog posts — WordPress, Medium, Substack ✅ Forums — Discussion boards, Reddit ✅ Thumbnails — Preview images for larger content

How to Convert

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

The tool generates high-quality JPEG images at 92% compression quality with white backgrounds.

JPEG Settings

Width Control

  • Custom width — Set desired pixel width (default: 800px)
  • Auto height — Maintains geographic aspect ratio
  • Recommended sizes:
    • 800px — Standard web graphics (50-150 KB)
    • 1200px — Social media, presentations (100-300 KB)
    • 1600px — Large displays (200-500 KB)
    • 2000px — High-quality printing (300-800 KB)

Quality & Compression

  • 92% quality — Balanced compression (visually lossless)
  • White background — JPEG doesn't support transparency
  • Optimized for maps — Preserves lines and boundaries
  • Small file sizes — Typically 5-10× smaller than PNG

Tips for Best Results

Choosing the Right Width

  • Web use: 800-1200px (best file size/quality ratio)
  • Social media: 1080-1200px (platform-optimized)
  • Email: 600-800px (fast loading)
  • Print: Use PNG instead for better quality

File Size Optimization

  • Lower width — Dramatically reduces file size
  • Simplify geometry — Fewer features = smaller files
  • Solid backgrounds — Better compression
  • Test different widths — Find size/quality sweet spot

Quality Considerations

  • Line thickness — Thicker strokes compress better
  • High contrast — Dark lines on white background
  • Avoid gradients — Creates compression artifacts
  • Simple colors — Fewer colors = better compression

When to Use JPEG

  • ✅ File size is priority
  • ✅ Transparency not needed
  • ✅ Web or social media use
  • ✅ Email attachments
  • ✅ Mobile optimization

When NOT to Use JPEG

  • ❌ Need transparency (use PNG)
  • ❌ Need editability (use SVG)
  • ❌ High-quality print (use PNG)
  • ❌ Need infinite scaling (use SVG)

FAQs

What width should I use? For web and social media, 800-1200px offers the best balance of quality and file size.

Does JPEG support transparency? No. JPEG always has a solid background (white by default). For transparency, use PNG.

Can I use JPEG for print? You can, but PNG or SVG are better for print quality. JPEG compression can show artifacts when printed.

Why is my image blurry? JPEG uses lossy compression. For crisp lines and perfect quality, use SVG or PNG.

How do I change the background color? JPEG exports with white backgrounds. To change color, open in an image editor (Photoshop, GIMP) and modify the background layer.

JPEG vs PNG? Use JPEG for smallest file sizes and web use. Use PNG when you need transparency or print quality.

JPEG vs JPG? They're the same format! "JPG" is just a shorter file extension. Windows originally required 3-letter extensions, so ".jpeg" became ".jpg".

Why are my lines not perfectly sharp? JPEG compression creates small artifacts around edges. For perfectly crisp lines, use SVG (vector) or PNG (lossless raster).

Can I adjust compression quality? The converter uses 92% quality, which provides excellent results for maps. For custom quality, export to PNG then convert with image editing software.
