Convert PNG to JPG to save space
PNG files of photographs are often huge because PNG compression is lossless. Converting them to JPG can shrink file sizes by 50–90% with no visible difference, which means faster websites, smaller email attachments and more space on your phone or cloud storage.
Choosing the quality level
| Quality | Typical use | Visual result |
|---|---|---|
| 95–100% | Printing, archiving | Indistinguishable, larger files |
| 85–90% | General use (recommended) | Indistinguishable for most photos |
| 70–80% | Websites, social media | Very good, much smaller |
| 50–65% | Thumbnails, previews | Visible softness on close inspection |
| Below 50% | Rarely useful | Blocky artifacts |
What about transparency?
PNG supports transparent pixels; JPG doesn't. When converting, transparent areas are filled with a background color:
- White: best for documents, product photos and most websites.
- Black: best for images that will appear on dark backgrounds.
If you need to keep transparency at a smaller size, use JPG to WebP, which accepts PNG input and supports transparency.
When PNG to JPG makes sense
- Photos exported as PNG from phones, editors or screenshot tools.
- Email attachments with size limits.
- Website images, to improve page speed and Core Web Vitals.
- Upload forms that only accept JPG.
- Bulk photo libraries taking up too much disk space.
When to keep PNG
Logos, icons, diagrams, screenshots with text and images with transparency usually look better and stay smaller as PNG.
