Bigjpg

Bigjpg is an AI super-resolution image enlarging and upscaling tool that uses Deep Convolutional Neural Networks. It is designed for users who need to enlarge images without quality loss, with a primary focus on anime-style artworks and illustrations, though regular photos are also supported. The tool intelligently reduces noise and serration in images, aiming to preserve colors, details, and edges while minimizing blur, "glitter," or visible doubling. It offers a web-based interface and downloadable apps for Windows (64-bit and 32-bit), Mac, iOS, and Android, as well as an API accessible after logging in. Free users can upload images up to 3000x3000 pixels and 5MB, while paid users have a 50MB limit. Processing speed varies based on original image size, enlarging configurations, server traffic, and time of day; an estimated remaining time is shown at the start, though actual processing is often shorter. The tool is intended for individuals or developers who need to enlarge images—especially anime or illustration art—while maintaining quality, and it supports batch processing through a login feature for faster and more stable use.
