Avifkit

avifkit is a free, browser-based AVIF image converter that solves the problem of converting AVIF files to more widely supported formats like JPG, PNG, or WebP. It addresses privacy concerns by performing all conversions entirely on the client side, meaning no files are ever uploaded to a server. This makes it ideal for privacy-conscious users, web developers, designers, photographers, and content creators who need to manage image format compatibility without compromising data security. It supports batch conversion (up to 30 files), adjustable quality settings, alpha channel preservation, and ZIP downloads for bulk results. Built with WebAssembly for instant speed, it offers a secure and efficient solution for AVIF conversion.
