The PNG image format is finally getting a major upgrade after more than two decades. This new update brings support for HDR, animation, more color options, and metadata. So PNG now becomes even more powerful and modern.
The World Wide Web Consortium (W3C) has released the third edition of the PNG (Portable Network Graphics) format. This update adds support for animations, Exif metadata, and HDR images. HDR is made possible using a method called CICP. It adds color space info with just four bytes of data, so HDR can be added without making the file too large.
Modern web browsers are already ready for this update. Browsers like Chrome, Edge, Firefox, and Safari can now show HDR PNGs properly. If an image includes CICP data, it will appear brighter and more vivid than older versions.
Animation support in PNG is not new. It was first added by developers back in 2001. Firefox has been able to show animated PNGs for years. But this is the first time animation has been added to the official PNG specs. Animated PNGs are better than GIFs in terms of color, but they can also be larger in size.

Another big improvement is support for Exif metadata. Photographers can now embed important details like GPS, copyright, and camera info directly into PNG files. Tools like Photoshop, macOS, iOS, and many video editors already support this.
PNG was first launched in 1995 as a free alternative to GIF. It came after Unisys said it would start charging fees for using the GIF format. PNG was made to offer high-quality, lossless images without any licensing fees. Over time, it became a go-to format for clear images and transparency.
This latest update was made with help from many big names, including Google, Apple, Adobe, NBCUniversal, and the BBC. There are already plans for more updates. The next version may improve how HDR and SDR images work together, and future updates could improve compression as well.
