Convert APNG (Animated PNG) to AVIF

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.

AVIF, or AV1 Image File Format, is a modern image format derived from the AV1 video codec developed by the Alliance for Open Media. It is designed to deliver high-quality images with superior compression efficiency compared to traditional formats like JPEG and PNG. This format supports advanced features such as HDR (High Dynamic Range), WCG (Wide Color Gamut), 10-bit color depth, and alpha transparency, making it ideal for web developers and digital content creators seeking to optimize performance and visual fidelity. Introduced in 2018, AVIF has rapidly gained adoption due to its open-source nature and effectiveness in reducing file sizes without compromising quality.
