Key takeaways

  • Use JPG for photos, blog images and social media images where small file size matters.
  • Use PNG for transparent backgrounds, logos, icons, UI graphics and crisp screenshots.
  • For website speed, compress images and consider WebP when possible.

What is the difference between JPG and PNG?

JPG and PNG are both popular image formats, but they are designed for different types of images. JPG uses lossy compression, which means it can make photos much smaller by removing some image data. PNG uses lossless compression, which keeps sharper details and supports transparency, but usually creates larger files.

This is why JPG is common for photography, blog visuals and web galleries, while PNG is common for logos, icons, screenshots, transparent graphics and interface elements.

Simple rule: Use JPG for realistic photos. Use PNG for graphics that need sharp edges or transparency.

Warning: Re-saving a JPG many times can reduce quality because JPG compression is lossy.

How to choose JPG or PNG

When in doubt, decide based on the purpose of the image. If you need the smallest practical file for a photo, choose JPG. If you need transparency or crisp graphics, choose PNG.
