Bigjpg - AI Super-Resolution lossless image enlarging / upscaling tool using Deep Convolutional Neural Networks

What

Bigjpg is an AI image upscaling tool that enlarges images using deep convolutional neural networks. It is designed to reduce noise and serration during enlargement so images can be scaled up with less blur, less visible noise, and better preservation of lines and colors than conventional resizing methods.

The product serves users who need higher-resolution versions of artwork, illustrations, anime images, and standard photos. Its workflow is straightforward: upload an image, choose image type, select an upscaling ratio and noise reduction level, then download the processed result. Based on the page, Bigjpg is positioned as a self-serve web and app-based image enlarger with consumer-friendly plans and an API for programmatic use.

Features

• AI super-resolution upscaling — Uses deep convolutional neural networks to enlarge images while aiming to preserve edges, colors, and detail.
• Artwork and photo modes — Lets users choose between illustration-style images and regular photos so processing can better match image characteristics.
• Multiple enlargement levels — Supports 2x, 4x, 8x, and 16x upscaling, with higher ratios available on paid plans.
• Adjustable noise reduction — Offers several noise reduction settings, helping users balance cleanup against detail retention.
• Web, desktop, and mobile access — Provides browser-based use plus Windows, Mac, iOS, and Android apps for different working environments.
• API for automation — Exposes task creation, status query, and retry endpoints so teams can embed image upscaling into software workflows.

Helpful Tips

• Test with image type settings first — Bigjpg explicitly distinguishes between artwork and photos, so selecting the correct mode is likely important for output quality.
• Use paid tiers for operational workloads — If you need batch processing, parallel enlarging, larger files, or higher ratios, the paid plans are materially more suitable than the free plan.
• Plan around processing variability — The site notes that completion time depends on original size, chosen settings, and server traffic, so it is better treated as asynchronous processing rather than instant resizing.
• Account login matters for workflow continuity — Logged-in users can use offline enlarging and access history, while anonymous sessions require keeping the browser open to avoid losing results.
• Review data retention requirements — The page states uploaded and enlarged images are automatically deleted after 3 days, which may be useful for temporary jobs but should be checked against internal retention needs.
