What is HEIF?
HEIF (High Efficiency Image Format) is a modern image format designed for advanced compression, superior image quality, and efficient storage. Unlike JPEG, HEIF supports both lossy and lossless compression, significantly reducing file sizes while maintaining excellent visual fidelity. It offers features like alpha transparency, animation, and HDR (High Dynamic Range), making images vibrant and versatile across devices. Although HEIF has limited to no compatibility with older systems, it's widely adopted by newer platforms, especially in mobile photography and digital media, providing optimized performance and richer, high-quality visuals.
What is AVIF?
AVIF (AV1 Image File Format) is a modern, high-efficiency image format developed by the Alliance for Open Media (AOM). It offers superior compression compared to JPEG, WebP, and PNG, delivering smaller file sizes with better image quality. AVIF supports both lossy and lossless compression, HDR (High Dynamic Range) imaging, and alpha transparency, making it ideal for web graphics, professional photography, and digital media. While AVIF is not yet universally supported, modern browsers and platforms are increasingly adopting it due to its excellent visual fidelity and optimized performance for web use.
