Bigjpg is an AI-powered super-resolution tool that enlarges images using Deep Convolutional Neural Networks. Instead of simply stretching pixels, it reconstructs lines, colors, and fine details, making it especially effective for anime-style artwork, illustrations, and regular photos. The platform supports upscaling up to 16× on paid plans, with adjustable noise reduction and dedicated Artwork and Photo modes. The service offers a free tier with 20 images per month and 4× enlargement, while paid plans provide up to 2000 images per month, 50MB uploads, high-priority processing, offline enlarging, and batch or parallel workflows. Premium members also get access to a REST API for programmatic image upload, enlargement, and result queries, complete with cURL and Python examples for integration. Bigjpg runs in the browser and offers native iOS and Android apps, making it convenient for artists, designers, and content creators who need clean high-resolution versions of their visuals. Uploaded files are automatically deleted within 24 hours for free accounts and 72 hours for premium accounts, and all image links are encrypted.
