Upscayl

Upscayl is an AI image upscaler for people working with small photos, illustrations or other low-resolution images. Its desktop app processes images locally, with a separate cloud offering for work across devices.

• Upscaling models: Choose different models to enlarge images according to the kind of result you need.
• Batch processing: Apply upscaling to a collection of images in one operation.
• Double upscaling: Run an image through a second upscaling pass to enlarge it further.

The desktop app is free and open source under AGPL-3.0. It runs on Linux, macOS 12 or later, and Windows 10 or later. A Vulkan-compatible GPU is required, and many integrated GPUs don't work.

Upscayl Cloud handles images through a hosted service. Its capabilities include face enhancement, image editing, image generation and cloud storage; those features belong to the cloud offering.
