When to use PNG vs JPG
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

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.
