How to Convert PNG to JPG (and When You Should)
Learn how to convert PNG to JPG, when each format is the right choice, and how to shrink your images without losing quality.
Knowing how to convert PNG to JPG can dramatically shrink your image files and speed up your website. Both are everyday image formats, but they are built for different jobs — and choosing the right one is the difference between a fast page and a slow one.
PNG vs JPG: the core difference
PNG is lossless and supports transparency, which keeps sharp edges perfect but makes files large. JPG (JPEG) uses lossy compression that throws away detail your eye barely notices, producing much smaller files. That trade-off is why photos are almost always JPG and logos are usually PNG.
Which format for which job
| Format | Best for |
|---|---|
| JPG | Photos, banners, large images. |
| PNG | Logos, icons, transparent graphics. |
When you should convert PNG to JPG
- The image is a photo, where transparency is not needed.
- The PNG file is large and slowing your page down.
- You are uploading many images and want to save bandwidth.
One thing to watch out for
JPG does not support transparency. If your PNG has transparent areas, they will turn white after converting — so keep the original PNG for anything that needs a see-through background.
