Convert PNG to JPG when the image is a photo or a busy picture without transparency: the JPG will usually be several times smaller and look the same. Keep PNG (or use WebP) when the image has a transparent background, sharp text, a logo, a screenshot or flat colours, because JPG blurs edges slightly and replaces transparency with a solid background, usually white or black. When converting, make sure transparent areas become white rather than black, and use a high quality setting (our converter uses 90%) so text and edges stay clean.
- Photos saved as PNG are often 3 to 10 times bigger than they need to be.
- JPG does not support transparency. Transparent areas become a solid colour.
- Logos, icons and screenshots usually look better as PNG.
- WebP can do both: small files and transparency.
- Convert in seconds with the free Image Converter.
The logo with the black box
A bakery owner downloads his new logo from the designer: a lovely PNG with a transparent background. A printing shop asks for a JPG, so he converts it with the first app he finds. On the printed menu, his logo sits inside an ugly black rectangle. The transparent parts did not disappear. They were filled with black.
Meanwhile, his website loads slowly because the cake photos in the gallery are 4 MB PNG files. He had the two formats exactly the wrong way round. Once you know what each is good at, the choice is easy.

What about WebP?
WebP supports both lossy compression (like JPG) and transparency (like PNG), usually with smaller files than either. It is ideal for your own website. For uploads to forms, printers and older software, JPG and PNG are still the safest choices. More in JPG vs PNG vs WebP and AVIF vs WebP.

Frequently asked questions
Should I convert PNG to JPG?
Yes for photos and busy images without transparency, because JPG files are much smaller. Keep PNG for logos, screenshots and transparent images.
What happens to transparency when converting PNG to JPG?
JPG does not support transparency, so transparent areas are filled with a solid colour, usually white or black.
Does converting PNG to JPG reduce quality?
JPG is lossy, so there is a small loss, mostly visible around sharp text and edges. At high quality settings, photos look the same.
Why is my PNG photo so large?
PNG uses lossless compression, which is inefficient for photos. Converting to JPG or WebP usually cuts the size dramatically.
Is WebP better than PNG and JPG?
For websites, often yes. WebP supports transparency and lossy compression with smaller files, but some forms and older software still require JPG or PNG.
