PNG to JPG
This lesson is part of Web Developer Tools · All levels
Summary
PNG to JPG conversion converts lossless images to smaller lossy formats, especially for photos. Since JPG does not support transparency, the alpha area will be filled with the selected background color, usually white. Use a high-quality image and save the original PNG if you need transparency or re-editing.
Key points
- PNG transparency will disappear and the background color will be replaced.
- JPG is suitable for photos, not for sharp text or logos
- The 80-90 quality usually provides a balance of size and detail
- Repeated compression can cause artifacts around the edges
- Save the original PNG file as master
