PNG

Overview

PNG stores raster images losslessly using deflate compression. It supports an alpha channel for smooth transparency and is the default choice for UI assets, logos, and screenshots that must keep every pixel intact.

Typical use cases

• Logos and UI assets
• Screenshots
• Images with transparency
• Lossless web graphics

Advantages

• Lossless pixels with an alpha channel
• Universal support across browsers and devices
• Reliable for logos, UI assets, and screenshots

Disadvantages

• Larger files than lossy formats for photos
• No native CMYK
• Animation requires APNG support

How to open or use it

Open PNG files in any browser, image viewer, or design tool. Most operating systems open PNG natively, and editors such as Photoshop, GIMP, and Figma can create or modify them.
