Images play a vital role in digital content, whether it’s websites, social media, branding, or design. Among all image formats, PNG (Portable Network Graphics) stands out for its high quality and transparency support. In this detailed guide, you’ll learn what PNG format is, its advantages, disadvantages, real-life use cases, and when you should or shouldn’t use it.
What is PNG Format?
PNG stands for Portable Network Graphics. It is a lossless image format, which means it preserves image quality even after compression. PNG was developed as an improved, open-source alternative to the GIF format and is widely used across the web today.
Unlike JPG, PNG does not lose quality when saved or edited multiple times. It also supports transparent backgrounds, making it a preferred choice for logos, icons, UI elements, and graphics.
In simple terms, PNG is an image format designed for clarity, sharpness, and precision, especially where image quality matters more than file size.
