AI image super-resolution
Uses deep convolutional neural networks to reduce noise and serration while enlarging images, with a focus on preserving edges and color.
Bigjpg
RevendiquerBigjpg is an AI image upscaling service for anime artwork, illustrations, and photos, with browser processing, history, API access, and paid high-volume options.
Overview
Bigjpg is an AI image upscaling service that enlarges user-provided images with deep convolutional neural networks. Its core purpose is to increase image size while reducing the blur, noise, and serration that often appear in conventional enlargement tools.
The service is positioned around anime-style artwork and illustrations, but it also supports regular photos. Users can upload images through the website, log in to access history and API features, and choose settings such as image type, noise reduction, and enlargement ratio before processing.
Features
Artwork and photo support
Supports anime-style artwork and illustrations, while also accepting regular photos.
Configurable processing options
Offers enlargement settings for image type and noise reduction, with options from none to highest and scale choices up to 16x on paid plans.
API access
Provides an API for task creation, status queries, and retries after login, with example calls shown on the site.
Offline enlarging
Supports offline enlarging for logged-in users, so completed images are not lost if the browser is closed.
Higher-volume workflows
Paid plans add parallel enlarging and batch mode for higher-volume workflows.
Use Cases
Upscaling anime artwork
Helpful for artists and fans who need to enlarge anime-style images or illustrations while keeping lines and flat color areas intact.
Enlarging photos
Useful for users who want to prepare a low-resolution photo for larger display or printing without using general-purpose enlargement tools.
Account-based image processing
Fits logged-in workflows where users need to revisit previous jobs, retry failed tasks, or access enlarging history from the account dashboard.
High-volume enlarging
Appropriate for repeat processing of multiple files, especially when paid-plan features like batch mode and parallel enlarging are needed.
API-driven automation
Suited to developers who want to integrate image enlargement through the API endpoints shown on the site.
