PNG to JPG: a big win for photos, a mistake for graphics
A PNG photo converted to JPG can lose 80 percent of its size. A PNG logo converted to JPG just looks worse.
PNG and JPG are built for different content and using the wrong one is the most common image mistake there is. PNG is lossless and holds sharp edges perfectly, which makes it right for logos, screenshots, diagrams and anything with text. JPG is lossy and excellent at photographs, where the eye does not notice the discarded data.
So converting a photograph from PNG to JPG is a large win, often 80 percent smaller with no visible difference. Converting a logo or a screenshot to JPG is a mistake, because JPG puts visible noise around sharp edges. The other thing to know: JPG has no transparency. Anything transparent becomes a solid colour, usually white or black. The converter is in ToolHub.
PNG to JPG: the facts that matter
| Best for | Photographs stored as PNG |
| Wrong for | Logos, screenshots, diagrams, anything with text |
| Transparency | Lost. Becomes a solid colour |
| Typical photo saving | Up to 80 percent |
| Better alternative | WebP, which handles both cases |
How to do it, step by step
- 1Look at the image and decide what it is. Photograph, or graphic with sharp edges and text?
- 2If it is a photograph, open the PNG to JPG converter in ToolHub.
- 3Check whether it has transparency. If it does, decide what background colour you want, because you are getting one.
- 4Convert at around 85 percent quality and compare the file sizes.
- 5If it is a logo, screenshot or diagram, stop. Keep the PNG, or convert to WebP instead.
Three things worth knowing
- The rule: photos as JPG or WebP, graphics and text as PNG or WebP.
- Screenshots should stay PNG. JPG makes UI text look dirty.
- WebP sidesteps the whole decision, since it handles photos and transparency both.

WebP beats JPG and PNG at the same visual quality. Support is no longer the issue it was, but there are still two cases to avoid it.
