Why Convert PNG to JPEG?
Converting PNG to JPEG dramatically reduces file size, often by 60-80%. This makes it ideal when you need smaller images for websites, email, or storage and don't require transparency.
Common Use Cases
- Reducing website image sizes for faster page loads
- Preparing photos for email attachments
- Uploading to platforms that don't support PNG well
- Saving storage space on large photo collections
Source Format
PNG
Portable Network Graphics
PNG is a lossless raster image format that supports transparency. It is widely used for web graphics, screenshots, and images that require crisp edges or transparent backgrounds.
+ Lossless compression preserves every pixel
+ Full alpha transparency support
+ Universally supported across all browsers and platforms
- Larger file sizes compared to lossy formats like JPEG or WebP
- Not efficient for photographs with complex color gradients
Target Format
JPEG
Joint Photographic Experts Group
JPEG is the most widely used lossy image format, optimized for photographs and complex images with smooth color transitions. It achieves excellent compression ratios at the cost of some quality loss.
+ Excellent compression for photographs
+ Universally supported everywhere
+ Adjustable quality-to-size ratio
- Lossy compression degrades quality with each save
- No transparency support
Quality & Size Notes
JPEG is lossy, so some quality is lost during conversion. Use quality 85-95 for a good balance. Transparent areas in your PNG will be flattened to a white background.
Frequently Asked Questions
Does converting PNG to JPEG reduce quality?
Yes, JPEG uses lossy compression. However, at quality settings of 85 or above, the difference is often imperceptible for photographs. The tradeoff is significantly smaller file sizes.
What happens to transparency when converting PNG to JPEG?
JPEG does not support transparency. Any transparent areas in your PNG will be converted to a white background.
When should I keep PNG instead of converting to JPEG?
Keep PNG when you need transparency, when your image contains text or sharp edges (logos, screenshots), or when lossless quality is critical.
