Face Swapper is an AI-powered tool that allows users to make production-quality face swaps. It uses artificial intelligence to detect faces on photos and replace them with other faces of the user's choice. It supports images up to 5 MB with faces up to 1024*1024 px in size and returns images of the same size and quality as the source image. It also features multiswap, which allows users to replace several faces in the same photo at once, and Smart Upscaler, which uses AI to enhance image resolution.
