Bigjpg
AI image enlarger that upscales artwork and photos up to 16x while reducing noise and jagged edges.
Bigjpg is an AI image enlarger that uses deep convolutional neural networks to upscale anime artwork, illustrations and photos by 2x or 4x, and by 8x or 16x on paid plans, while reducing noise. Bigjpg is used by selecting images, choosing the image type, scale and noise reduction level, then downloading the enlarged file.
Best for Illustrators and anime artists who need to enlarge drawings without blur, and developers who want to automate upscaling through an API.

What is Bigjpg?
Bigjpg is an image enlargement service that uses deep convolutional neural networks to increase resolution. Instead of stretching existing pixels, it redraws edges, colour areas and small details, and the developers say the approach is tuned for anime artwork and illustration, with ordinary photographs supported too. Before a job starts you choose the image type, the scale factor and how strongly noise should be reduced. The tool runs in a web browser and is also distributed as Windows, Mac, iOS and Android apps. Free use is restricted in file size, speed and magnification, whereas paid accounts get high-performance servers, larger uploads, the highest scale factors, simultaneous jobs and access to an API. The site interface is offered in 19 languages.
