About

Bigjpg is a web-based AI image enlarger that increases the resolution of anime-style artwork, illustrations, and photographs without the blurriness and blockiness that appear when pixels are simply stretched. The service uses deep convolutional neural networks to perform super-resolution, which means it reconstructs lines, colors, and fine details rather than duplicating existing pixels.

Users upload an image through the website or one of the official desktop and mobile apps, choose an image type (artwork or photo), select an enlargement factor and a noise-reduction level, and download the result. The tool is aimed at anyone who needs small or low-quality images rendered at larger sizes — for wallpapers, prints, or high-resolution screens. Bigjpg is available in roughly nineteen languages, offers a documented API for batch processing, and provides a free tier alongside paid subscription plans. Support contact runs through the email address [email protected].

Key Features

Neural-network upscaling: Deep convolutional networks rebuild lines, colors, and details, producing sharper edges and cleaner output than basic interpolation.
Up to 16x enlargement: The service supports 2x, 4x, 8x, and 16x scale factors, letting users reach multi-thousand-pixel dimensions from small sources.
Adjustable noise reduction: Five levels (none, low, medium, high, highest) let users suppress JPEG artifacts and grain while preserving detail.
Artwork and photo modes: A dedicated setting switches the algorithm between anime-style line art and photographic content.
Multiple output formats: Results can be saved as WebP, JPG, or PNG in addition to the default format.
Cross-platform apps: Native apps are offered for Windows, macOS, iOS, and Android, alongside the browser interface.
API with batch support: A documented API with key authentication supports automated, batch, and parallel upscaling workflows, including a Python tutorial for large jobs.

Pricing & Fees

  • Pricing: A free plan allows 20 images per month at up to 4x. Paid plans are Basic at $6 USD for 2 months (500 images/month), Standard at $12 USD for 6 months (1,000 images/month), and Premium at $22 USD for 12 months (2,000 images/month).
  • Free tier: The free plan works without payment but uses slower shared servers and limits uploads to 5MB per image and a 4x maximum ratio.
  • Paid limits: All paid plans raise the upload cap to 50MB, unlock 8x and 16x enlargement, enable parallel and batch processing, and run on high-performance servers with top priority.
  • Payments: Stripe, WeChat Pay, and Alipay are accepted on the site; in-app purchases via Apple Pay or Google Wallet are available through the mobile apps, and cryptocurrency payments can be arranged by email.
  • Offline enlarging: Both free and paid plans list offline enlarging as supported, alongside the cloud service.

Who It's For

Bigjpg suits digital artists and manga or anime illustrators who need line art enlarged for wallpaper-sized exports, photographers restoring low-resolution shots, and print designers preparing files for A4-to-poster output. The API and batch mode make it practical for developers and studios processing large image libraries, such as game asset pipelines or archive digitization. Casual users can handle occasional enlargement on the free plan, while professionals benefit from higher quotas and priority processing.
