What is PNG?
PNG (Portable Network Graphics) is a lossless format introduced in 1996 as a replacement for GIF. It preserves full image quality while supporting an alpha channel for true transparency, which has made it the default for icons, logos, screenshots, and UI elements β anywhere sharp edges and transparency matter. PNG can actually compress better than JPG for simple graphics, but files can grow very large for color-rich photographs. All major browsers and operating systems support it natively.
When should I use PNG?
PNG is the answer whenever you need transparency. Website logos, app icons, UI mockups, screenshots, charts, diagrams β anywhere text and lines need to stay crisp. Because it's lossless, you can edit and re-save without cumulative quality degradation, making it great for intermediate design files. Just be mindful that saving photographs as PNG produces much larger files, so consider the final use case first.
