What is PNG?

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF.

What is JFIF?

JPEG File Interchange Format, common JPEG container variant — stored as image/jpeg — uses lossy encoding to handle digital photography, web images, legacy jpeg files. Typical file sizes: varies by content.

When Should You Use PNG vs JFIF?

Use PNG When...

Reach for PNG when your priority is graphics, logos, images requiring transparency — its uncompromising quality ensures every detail is preserved.

Use JFIF When...

Reach for JFIF when your priority is digital photography, web images, legacy jpeg files — its efficient compression makes sharing fast and storage minimal.

PNG vs JFIF: Key Differences
