- Excellent for photographs with gradients and colors
- Smaller file sizes for photos
- Universal browser support
PNG (Portable Network Graphics)
Best for: Graphics, logos, screenshots, images needing transparency
- Uses lossless compression — no quality loss
- Full alpha transparency support
- Perfect for sharp text and lines
- Larger file sizes than JPEG
- Universal browser support

Frequently Asked Questions
Which is better, PNG or JPEG?
Neither is universally better. Use JPEG for photographs (smaller files) and PNG for graphics with transparency or sharp text.
Why are PNG files so large?
PNG uses lossless compression to preserve every pixel perfectly. This is great for quality but results in larger files than JPEG's lossy compression.
Can I convert PNG to JPEG?
Yes, but you'll lose transparency. Use the Image Converter to convert PNG to JPEG — the tool will flatten transparency to a white background.
