What is it?

PNG (Taşınabilir Ağ Grafikleri), 1996 yılında patentli GIF formatına açık bir alternatif olarak oluşturulmuş kayıpsız bir raster görüntü formatıdır. JPG'nin aksine, PNG sıkıştırma sırasında görüntü verilerini asla atmaz, her pikseli tam olarak yakalandığı gibi korur.

PNG, tam alfa kanalı şeffaflığını destekler, yani pikseller tamamen şeffaf, tamamen opak veya aradaki herhangi bir seviyede olabilir. Bu, logolar, simgeler, kullanıcı arayüzü öğeleri ve şeffaf arka plana ihtiyaç duyan herhangi bir görüntü için standart seçim olmasını sağlar.

Frequently Asked Questions

Is PNG better than JPG?

It depends on the content. PNG is better for graphics, logos, and images with transparency. JPG is better for photographs where smaller file size matters more than pixel-perfect accuracy.

Why is my PNG file so large?

PNG uses lossless compression, so file sizes are larger than JPG. To reduce size without losing quality, use a PNG optimizer or convert to WebP for web use.

Does PNG support animation?

Standard PNG does not support animation. APNG (Animated PNG) is an extension that adds animation support, but it is not universally supported.

Can I convert PNG to JPG without losing quality?

Converting PNG to JPG always introduces some quality loss because JPG uses lossy compression. Any transparent areas will be filled with white. If quality is critical, keep the PNG.

What is the difference between PNG-8 and PNG-24?

PNG-8 supports 256 colors (like GIF) and produces smaller files. PNG-24 supports millions of colors with full alpha transparency. Use PNG-24 for most modern use cases.
