Why convert PNG to JPG
PNG is great for logos and screenshots but gets heavy with photos. JPG makes a photo 3 to 10 times smaller with a loss that is hard to see at 85 to 90% quality. Many websites and print shops also ask for JPG.
| JPG quality | Relative size | Use |
|---|---|---|
| 100% | 100% | Archive, print |
| 90% | about 40% | High-quality photo |
| 80% | about 25% | Website, email |
| 60% | about 15% | Thumbnail |
Transparency becomes a color
A JPG has no transparency channel, so every transparent pixel is blended with the background color you choose. For a half-transparent pixel the math is:
\[ \text{final pixel} = \text{color} \times \text{opacity} + \text{background} \times (1 - \text{opacity}) \]
A red at 50% opacity on white becomes a light pink. Pick a background close to wherever the image will be placed to avoid a visible halo.
Shrink the dimensions too
For a lighter file, cap the longest side at 2,560, 1,920 or 1,280 pixels. The tool only scales down and never enlarges. 1,920 px is enough for almost any website, and 1,280 px for a phone screen.
3 real-life examples
A screenshot that is too heavy
Your 6 MB PNG screenshot is rejected by a form capped at 2 MB. Convert it to JPG at 85% and it drops below 1 MB.
A transparent logo on white
You must send a transparent PNG logo to a printer that wants JPG. White background, 100% quality: the logo looks identical on paper.
A WebP photo from the web
An image you saved from a site is WebP and your software will not open it. Drop it here and get a JPG that opens everywhere.
