PNG vs JPG: Which Image Format Should You Use?

The Short Answer

• Use JPG for photos and images with lots of colors
• Use PNG for graphics, logos, and images that need transparency

Key Differences

Compression

JPG uses lossy compression — smaller file, slight quality reduction. For most photos, completely acceptable. PNG uses lossless compression — no data is discarded. Larger file, pixel-perfect quality. Crucial for logos and text-heavy images.

Transparency

PNG supports transparent backgrounds. JPG does not — it always has a solid background.

File Size

For photos, JPG files are typically 3–10x smaller than PNG. For simple graphics with few colors, PNG can be smaller.

When to Convert PNG to JPG

• The image is a photo (not a graphic or logo)
• You need to reduce file size for web performance
• Transparency is not needed
