Why convert PNG to JPG?
PNG is lossless, which makes it great for screenshots, logos and graphics with sharp edges, but it produces large files for photos and detailed images. Converting to JPG can shrink a file dramatically, which helps when an upload form has a size limit or you're emailing a batch of images.
When to keep PNG
- Transparency: JPG can't store transparent areas. Logos on transparent backgrounds should stay PNG.
- Text and line art: JPG compression can create faint smudges around sharp edges. For screenshots full of small text, use quality 95 or higher, or keep the PNG.
- Repeated editing: every JPG save loses a little detail. Edit the PNG and export to JPG at the end.
Recommended settings
| Use | Quality |
|---|---|
| Photos for sharing or social media | 80–90 |
| Screenshots with text | 92–100 |
| Meeting an upload size limit | 70–80 |

Frequently asked questions
Does converting PNG to JPG reduce quality?
Slightly, because JPG is lossy. At high quality settings the difference is rarely visible in photos, but can be noticeable around sharp text.
Why is my JPG bigger than the PNG?
Simple graphics with large flat areas of colour compress very well as PNG. For those images, JPG may not be smaller, and PNG is the better format.
