PNG vs JPG

PNG and JPG (JPEG) are the two most common image formats in ecommerce. Each has distinct characteristics that make it better suited for different purposes. Understanding when to use each format is essential for efficient image workflows.

PNG characteristics

• Supports transparency (alpha channel)
• Lossless compression: No quality loss when saved
• Larger file sizes than JPG
• Best for: Cutouts, graphics, images with text, design assets

JPG characteristics

• No transparency support
• Lossy compression: Some quality loss when saved
• Smaller file sizes than PNG
• Best for: Web photos, large images where transparency isn't needed

When to use each

Use PNG when you need transparency (cutouts for compositing, design assets) or when preserving quality is critical. Use JPG for web delivery when transparency isn't needed and file size matters.

WebP as an alternative

WebP is a newer format that offers better compression than both PNG and JPG while supporting transparency. Most modern browsers and platforms support WebP, making it a good choice for web delivery. Keep PNG masters for archives and design work.

Format workflow

A typical workflow: Keep high-resolution PNG masters with transparency for all your product cutouts. Export JPG or WebP versions for web use. This gives you flexibility while optimizing for performance.
