Why Convert PNG to AVIF
AVIF achieves up to 50% smaller files than WebP and 70% smaller than JPG at equivalent quality. It is the most efficient image format currently available for photographic content.
AVIF supports 10-bit and 12-bit color depths with HDR metadata, enabling vibrant, true-to-life images on HDR displays. Wide color gamut coverage exceeds sRGB for richer, more accurate colors.
Chrome, Firefox, Safari, and Edge all support AVIF images. Adoption is accelerating rapidly, and AVIF is becoming the preferred next-generation image format for the modern web.
AVIF includes a dedicated film grain synthesis tool that preserves the natural texture of photographs at a fraction of the file size. Grainy low-light photos maintain their character after compression.
AVIF supports alpha transparency and animated image sequences, combining the best features of PNG, GIF, and JPG into one format with dramatically better compression efficiency.

About the PNG Format
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It uses DEFLATE lossless compression, meaning every pixel is preserved exactly as intended — no visual information is discarded during encoding. PNG was developed by the web community and standardized by the W3C and ISO, making it one of the most trusted and universally supported image formats available.
PNG is best suited for screenshots, graphics, logos, and any image that requires transparency. Its support for a full alpha channel allows smooth, semi-transparent edges that blend seamlessly with any background. The main trade-off is file size — PNG files are significantly larger than JPEG for photographic content because no visual data is discarded. PNG does not natively support animation; for animated sequences, APNG (Animated Portable Network Graphics) serves as its extension.
