PNG vs JPG: Which Format Is Best?

PNG and JPG are both useful, but they are designed for different kinds of images. The wrong choice can either waste file size or remove details you need.

A simple rule helps: JPG is usually for photos, while PNG is for transparency, screenshots, diagrams, and graphics where crisp edges matter.

Complete guide

PNG strengths

PNG supports transparency and preserves crisp edges. It works well for icons, interface screenshots, diagrams, and images with flat colors.

The tradeoff is file size. A PNG photo can be much larger than a JPG photo with little visible improvement on a website.

JPG strengths

JPG is efficient for photographs and widely accepted across websites, email tools, forms, and devices. It can shrink large camera images substantially.

JPG does not support transparency and can create artifacts around text or sharp graphic edges when compressed aggressively.

Common mistakes to avoid

Do not save transparent graphics as JPG unless you are comfortable replacing transparency with a solid background.

Do not use PNG for large photo galleries unless there is a specific quality or transparency reason.

Conclusion

Choose PNG for transparency and crisp graphics; choose JPG for photos and compatibility when smaller file size matters.

FAQ

Can JPG have a transparent background?

No. Use PNG, WebP, or SVG for transparency.

Which is better for screenshots?

PNG is often better for screenshots with text or UI elements. WebP can also be efficient for web delivery.

Which is smaller, PNG or JPG?

JPG is usually smaller for photos. PNG may be smaller or cleaner for simple graphics with few colors.
