PNG vs JPG: Which Image Format Should You Use?

Quick Comparison

JPG (JPEG) uses lossy compression — smaller files but some quality loss. Best for photographs and complex images with many colors.

PNG uses lossless compression — larger files but perfect quality preservation. Best for graphics, logos, screenshots, and images needing transparency.

WEBP offers both lossy and lossless modes with better compression than both — ideal for web use but has slightly less universal support.

When to Use JPG

Use JPG for photographs, product photos, social media posts, email attachments, and any image where file size matters more than pixel-perfect quality. JPG is universally supported and produces the smallest files for photographic content. Most cameras save in JPG by default. For web use, JPG at 80-85% quality offers the best balance of size and appearance.

When to Use PNG

Use PNG when you need transparency (logos on different backgrounds), text-heavy images (screenshots, infographics), graphics with sharp edges (icons, UI elements), or any image that will be edited multiple times. PNG preserves every pixel exactly, making it ideal for design work. However, PNG files can be 5-10x larger than equivalent JPGs for photographs.

When to Use WEBP

Use WEBP for website images. It offers 25-35% better compression than JPG at equivalent quality and supports transparency like PNG. Modern browsers (Chrome, Firefox, Edge, Safari) all support WEBP. If you're optimizing a website for speed, converting images to WEBP is one of the easiest performance wins.
