PNG vs JPEG: The Essentials

Choosing the right format has a huge impact on image quality, file size, and performance. PNG and JPEG are the most common—but they’re built for different jobs. Understanding their strengths will help you avoid blurry photos, heavy pages, or broken transparency.

What Is JPEG Good For?

  • Photographs and gradients with many colors
  • Excellent lossy compression (tiny file sizes)
  • Adjustable quality for web performance
  • Not suitable for transparency or sharp UI assets

What Is PNG Good For?

  • Logos, UI, screenshots, and text with sharp edges
  • True transparency (alpha channel)
  • Lossless compression preserves every pixel
  • Larger files than JPEG for photos

How to Choose Quickly

  • Logos, icons, UI assets → PNG (keep transparency)
  • Need small and modern → try WebP or AVIF

Pro Tips

  • For screenshots, PNG beats JPEG (crisper text, no artifacts).
  • For hero photos and banners, JPEG at 75–85 is a great balance.
  • If you need transparency on the web, avoid JPEG—use PNG or WebP (lossless).
