AI image upscaling
Uses deep convolutional neural networks to reduce noise and serration so images can be enlarged without obvious blur or quality loss.
Overview
Bigjpg is an AI image enlargement tool that uses deep convolutional neural networks to upscale images while reducing noise and jagged edges. The homepage presents it as a lossless image enlarging and upscaling service for anime-style artworks, with photo support as well.
The product is built around a simple upload-and-process workflow in the web app, with additional app downloads for Windows, Mac, iOS, and Android. Logged-in users can use offline enlarging, view history, and access the API, while paid plans raise file-size limits and enlarging ratio limits compared with the free plan.
