Description	🔵 Portable Network Graphics, or .png, is a type of image. It’s good for the web. It keeps quality high when you save it and lets you make backgrounds see-through. That’s why it’s used for logos and icons online.
Technical details	🔵 Technically, PNG uses lossless compression. So, it doesn’t lose detail like a JPEG does. It can be simple black-and-white or very rich in color. A big plus is its alpha channel – it handles transparency really well, from solid to fully clear. This helps a lot with web design. The format supports millions of colors, and also has a 256-color mode for smaller files. PNG works best when you neeed clean, sharp edges and transparency.

Description	🔵 HEIF is essentially what happens when you take the high-end math from 4K video compression and apply it to still photos. Most people know it as those .heic files that popped up on iPhones a few years back. Developed by the MPEG crew, it’s not just a 'new JPEG'—it’s a much smarter container. It manages to cram way more visual data into a file that’s roughly half the size of an old-school JPEG, effectively ending the era of 'storage full' warnings for casual shooters.
Technical details	🔵 HEIF is an improvement over previous image formats, such as JPEG. It employs more efficient compression algorithms, resulting in smaller file sizes while maintaining image quality. Furthermore, HEIF can support features like transparency, alpha channels, and multiple images (like burst photos or Live Photos on iOS devices) within a single file. Opening HEIF files requires compatible software; popular image viewing and editing software like Apple Photos, Adobe Photoshop, and GIMP are examples. However, older software may not support HEIF natively. In these cases, users need to convert their files to a compatible format before use.What makes HEIF actually interesting is that it isn't a flat image. It’s a multi-layered box. Because it’s built on the HEVC algorithm, it natively supports things that JPEG could never dream of—like alpha channels for transparency or 'stacking' multiple frames into a single file for burst shots and Live Photos. The catch? It’s a total compatibility gamble. While the big players like Photoshop, GIMP, and Apple’s native apps have caught up, trying to open a HEIF on an older Windows machine or legacy editing suite is a recipe for frustration. You’re basically forced into a conversion workflow just to make the files 'talk' to older tech. It’s the classic 'early adopter' tax: you get incredible efficiency, but you’re stuck dealing with software that hasn't quite moved into the 2020s yet.
