Overview
What you provide
- Select a low-resolution image or folder and an available enlargement model.
What you get
- Upscayl exports locally enlarged images using AI upscaling models and a desktop interface.
Choosing this tool
Upscayl is useful for enlarging a catalog of low-resolution images on a compatible workstation. Its simple desktop flow is easier than configuring Real-ESRGAN directly, while Clipdrop is useful when you cannot run a local GPU tool. Upscayl does not turn an out-of-focus photo into verified original detail.
A decision worked through
A batch of 100 images does not consume 100 service credits in the desktop app. The practical decision is whether your GPU completes a representative sample acceptably; neither throughput nor recovered detail has been benchmarked in this review.

Setup & workflow
- Install the desktop release for your system and verify GPU compatibility.
- Upscale a small sample using a model suited to the image type.
- Compare at native pixels before starting the remaining folder batch.
Requirements & installation
- Install from the official releases, or use brew install --cask upscayl on macOS.
Limits & review
- A Vulkan-compatible GPU is required; many integrated GPUs and CPU-only machines are unsuitable. The README explicitly says the tool cannot correct focus or fully blurred images. Model and output rights still need review.
Your part
- Inspect text, faces and repeated textures for invented details before publishing an enlarged image.
