Bigjpg enlarges an image using AI super-resolution rather than stretching pixels directly, reconstructing lines, colours and fine detail so upscaled artwork and photos come out sharper and with less noise. It is tuned in particular for illustration and anime-style artwork alongside ordinary photos, supports enlarging up to 16 times the original size on paid tiers, and has an API for developers who want to build the upscaling into their own product, alongside newer AI Magic Upscaler, AI Photo Restoration and AI Video Enhancement tools.
The free plan runs on a shared, slower server with a 5 MB upload limit and no batch or offline processing, which suits occasional single-image use rather than a real workload. Payment options include WeChat Pay and Alipay alongside Stripe, suggesting the service has a China-connected user base or operator, though no separate company name beyond Bigjpg was found on the pages reviewed. As with any AI upscaler, the added detail is the model’s best reconstruction of what should be there, not a recovery of information that was never captured in the original image.
Free is $0, limited to a shared, slow server, 5 MB uploads and no batch processing. Basic is $6 for 2 months with 500 pictures, top priority processing and a 16x maximum ratio. Standard is $12 for 6 months with 1,000 pictures, marked as the best-selling tier. Premium is $22 for 12 months with 2,000 pictures. All paid tiers add high-performance servers, offline and parallel enlarging, batch mode and a 50 MB upload limit, and can be paid through Stripe, WeChat Pay or Alipay.
