Frequently Asked Questions

What is PNG compression?

PNG compression is a lossless technique that reduces file size without sacrificing image quality. It's especially effective for graphics with limited colors, text, and images requiring transparency.

When should I use PNG instead of JPG?

Use PNG for images that require transparency, graphics with text, logos, icons, screenshots, and any images that need perfect quality preservation.

Why are my PNG files so large?

PNG files can be large, especially for photographs or complex images with millions of colors. They store more data than JPG to maintain perfect quality and transparency.

Can PNG compression reduce image quality?

No. PNG uses lossless compression, which means no image quality is lost during compression - every pixel remains exactly the same.
