PNG Compression FAQ
What's the difference between PNG-8 and PNG-24?
PNG-8 supports up to 256 colors and is perfect for simple graphics, logos, and icons. PNG-24 supports millions of colors and is better for complex images, photographs, and detailed graphics.
Will compression affect PNG transparency?
No, PNG compression preserves transparency perfectly. Both PNG-8 and PNG-24 support transparency, with PNG-24 offering full alpha channel support for smooth transparency effects.
How much can I compress PNG files?
PNG compression typically achieves 20-80% file size reduction depending on the image content. Simple graphics with few colors compress better than complex photographic images.
Should I use PNG or JPG for photos?
For photographs, JPG is usually better due to smaller file sizes. Use PNG for photos only when you need transparency or want to preserve every pixel perfectly without any compression artifacts.
Are my PNG files secure during compression?
Absolutely. All compression happens locally in your browser. Your PNG files never leave your device, ensuring complete privacy and security of your images and graphics.
