bigjpg is an AI-powered image enlargement tool that uses deep convolutional neural networks to upscale images while preserving quality. It intelligently reduces noise and serration, making it particularly effective for anime and illustrations, though regular photos are also supported.
The web-based platform allows users to upload images and configure settings such as image type (art/photo), upscaling factor (2x, 4x, 8x, 16x), and noise reduction level. Free users can process up to 20 images per month with a maximum upload size of 5MB and 4x enlargement. Paid plans unlock higher limits, faster processing, offline enlarging, batch mode, and API access. Desktop (Windows, Mac) and mobile (iOS, Android) apps are available.
