Bigjpg is an online AI image upscaler that specializes in enlarging images (particularly artwork and anime-style images) without losing clarity. It uses deep convolutional neural networks, originally based on techniques like waifu2x, which are tuned to handle lines, colors, and details in illustrations and photographs.
With Bigjpg, users can upload a small or low-resolution image and choose an upscale factor (e.g.
, 2×, 4×, 8×) and a noise reduction level. The AI then processes the image to produce a larger version that looks smooth and detailed, rather than pixelated. This tool is especially popular among digital artists, anime fans, and photographers who need to blow up images for printing or high-res displays. It handles cartoon and anime images exceptionally well by preserving line art and flat colors, but also works on regular photos. The interface is straightforward: just upload, select settings, and wait for the processed result. Free users can process images up to a certain size, while larger resolutions are available via higher-tier accounts. Bigjpg demonstrates how AI can overcome the typical limitations of image enlargement, making it possible to zoom in or print images much bigger than originally designed while keeping them looking crisp.
