When to use PNG vs JPG

2 min read ·

PNG and JPG are the two most common image formats online, but they serve different purposes. When you have picked one, convert PNG to JPG or JPG to PNG in a couple of seconds.

JPG — Best for photos

  • Lossy compression — Some quality is lost on each save
  • Small file size — Great for photographs with complex color gradients
  • No transparency — Background is always opaque
  • 8-bit color — 16.7 million colors
  • Best for: Photos, screenshots with photographic content, social media images

PNG — Best for graphics

  • Lossless compression — No quality loss, pixel-perfect reproduction
  • Transparency support — Full alpha channel for see-through backgrounds
  • Larger files — Especially for photographic content
  • 8-bit or 24-bit color — With optional alpha channel
  • Best for: Logos, icons, screenshots, text-heavy images, anything with transparency

Quick decision guide

Content type Use
Photograph JPG
Logo or icon PNG
Screenshot of text/code PNG
Image with transparency PNG
Social media post (photo) JPG
Web graphic with solid colors PNG
Image for printing PNG (or TIFF)

Modern alternatives

Consider WebP as a replacement for both — it handles photos (lossy) and graphics with transparency (lossless) in a single format with smaller file sizes. AVIF offers even better compression but has slightly less browser support.

Try it on your own images: PNG to WebP, JPG to WebP, PNG to AVIF or JPG to AVIF.
