Bigjpg

Bigjpg is an AI-powered image enlarging and super-resolution tool that utilizes deep convolutional neural networks to reduce noise and preserve image quality. It is available as a web platform as well as through dedicated apps, providing both free and paid plans. The software is specifically aimed at processing anime artwork, illustrations, and regular photos.

• Uses deep convolutional neural networks for image noise reduction and upscaling
• Supports up to 16x image enlarging
• Provides dedicated handling for anime-style artworks and illustrations alongside regular photos
• Includes API access for automated tasks
• Supports batch processing and parallel enlarging on paid plans
• Offers offline enlarging capabilities for logged-in users
• Maintains an enlarging history viewable after logging in

Pros

• Retains colors and edges well for anime artwork and cartoon illustrations
• Allows free users to process images up to 3000x3000px and 5MB
• Encrypts image links and automatically deletes uploaded files within 24 hours for free accounts and 72 hours for premium accounts
• Provides server location switching between Mainland China and the United States to help improve download speeds

Cons

• Free users must keep their browser open during the enlarging process or the result will be lost
• Free accounts are limited to a slow shared server with a maximum enlarging ratio of 4x and 20 pictures per month
• There is a small chance of enlarging failure depending on network environment and server traffic
• Default server is located in Mainland China, which may require manual server location changes for users elsewhere

Bigjpg fits individuals and developers who need to upscale anime artwork, illustrations, or regular photos without introducing significant blur or noise. It suits users who can benefit from automated workflows via API access or batch processing options. It is a poor fit for users seeking entirely local, offline-only desktop processing without any cloud dependency or account creation.

Bigjpg uses a freemium model with a free tier and several paid one-time payment options. The Free Plan allows 20 pictures per month on a slow shared server with a 5MB max upload size, 4x max enlarging ratio, and offline enlarging. The Basic plan costs $6 USD for 2 months, providing 500 pictures, top priority speed, high-performance server access, 50MB max upload size, 16x max enlarging ratio, parallel enlarging, and batch mode. The Standard plan costs $12 USD for 6 months with 1000 pictures and the same high-performance features. The Premium plan costs $22 USD for 12 months and includes 2000 pictures along with all high-performance features.

Unlike traditional image editing software such as Photoshop, which can leave enlarged images looking fuzzy with visible blur and noise, Bigjpg uses deep convolutional neural networks with custom algorithms adjusted specifically for image lines and colors. This approach prevents doubling and glitter effects while preserving original colors. Furthermore, it supplies both web interfaces and an API for programmatic integration, setting it apart from manual-only editors.

Bigjpg provides an API accessible via curl and Python demos. The platform offers downloadable apps for Windows 64-bit, Windows 32-bit, Mac, iOS, and Android, with mobile app downloads also available via Google Play or WeChat QR code scanning. Supported payment methods include Stripe, WeChat Pay, and Alipay.
