JPG (JPEG) — Best for Photographs

JPG is the most widely supported image format in the world. It uses lossy compression, meaning some image data is discarded to achieve small file sizes. For photographs and images with complex colour gradients, this loss is virtually invisible at quality settings of 75% or above.

  • ✅ Very small file sizes
  • ✅ Universally supported on all devices, browsers and platforms
  • ✅ Perfect for photographs and real-world imagery
  • ❌ Does not support transparency
  • ❌ Quality degrades each time you save (avoid re-saving JPGs repeatedly)
  • ❌ Not ideal for text, logos or sharp edges

Use JPG for: photographs, product images, backgrounds, hero images on websites.

PNG — Best for Graphics with Transparency

PNG uses lossless compression — no image data is discarded. This means perfect quality at all times, but larger file sizes than JPG. PNG supports transparency (alpha channel), making it the only choice when you need a transparent background.

  • ✅ Perfect quality, no compression artefacts
  • ✅ Supports full transparency
  • ✅ Ideal for logos, icons and text-heavy images
  • ❌ File sizes much larger than JPG for photographs
  • ❌ Not ideal for complex photographs

Use PNG for: logos, icons, screenshots, graphics with text, images needing transparent backgrounds.

WebP — The Modern Winner for Websites

WebP is a modern image format developed by Google. It supports both lossy and lossless compression and produces files that are typically 25–35% smaller than equivalent JPG or PNG files at the same visual quality. It also supports transparency like PNG.

  • ✅ Smallest file sizes — faster websites
  • ✅ Supports transparency
  • ✅ Supported by all major browsers (Chrome, Safari, Firefox, Edge)
  • ✅ Both lossy and lossless modes available
  • ❌ Not universally supported in older software and email clients
  • ❌ Not ideal for print (use JPG or PNG for print)

Use WebP for: all website images where loading speed matters. It is the best default for web in 2026.

Quick Reference — When to Use Each

  • Website photos: WebP (first choice) or JPG
  • Website logos and icons: WebP or PNG (if transparency needed)
  • Social media posts: JPG at 80–85% quality
  • Email attachments: JPG (universal support)
  • Print documents: JPG at 100% quality or PNG
  • Screenshots: PNG (preserves text sharpness)
  • Transparent backgrounds: PNG or WebP
