Improving your images with AI. An open source desktop tool that enlarges and restores low-resolution files using computer vision models.
Open it
The verdict.
Upscayl is the rare tool that is both genuinely free and genuinely good. If you need to rescue old photos, blow up a small logo, or clean up compressed product shots before print, this open source desktop app does the job locally without a subscription or a watermark. It will not turn a thumbnail into a magazine cover, but for the price of nothing, it is the first thing you should reach for.
Pricing, straight.
Upscayl keeps this refreshingly simple. The core desktop app is free and open source. There is a separate Upscayl Cloud offering promoted on the site for users who want processing and storage handled remotely, but the download you run on your own machine costs nothing.

What it actually does.
Fast local processing
Runs on your own hardware and leans on your GPU. Upscayl claims roughly 10x faster throughput than older tools.
Color accuracy for print
Preserves color fidelity through the upscale, which matters when the output is headed to a physical print run.
Batch upscaling
Point it at a folder and process an entire set of images in one job instead of one file at a time.
Up to 16x resolution
Scale small source files aggressively, with a Double Upscayl option to run a second pass for extra detail.
Model customization
Swap between different AI models depending on whether you are working with photos, art, or illustrations.
Universal compatibility
Available across Windows, macOS, and Linux, so the same workflow follows you between machines.
Who it is for.
Creators and designers get the clearest payoff. Any time you inherit a logo or asset that only exists at a tiny size, Upscayl saves you from tracking down the original file or recreating it from scratch.
Businesses can push compressed product shots to a usable resolution before they hit a high-density display or a printed catalog, without paying per image.
Artists restoring old scans and family photos will appreciate the model options tuned for different source material.
Developers benefit from the open source codebase, which means the tool can be inspected, self-hosted, or built into a larger pipeline.
The honest part.
- It is a desktop app, not a web tool. Despite the URL, the free product is a download you install locally. If you wanted browser-based upscaling with nothing to set up, that is the paid Cloud tier.
- Performance depends on your GPU. The 10x speed claims assume decent hardware. On an older laptop, large batches or 16x jobs can be slow.
- Upscaling is not magic. The AI invents plausible detail; it does not recover information that was never there. Faces and fine text can look smeared or artificial when the source is very degraded.
- No listed integrations. There are no native connectors to design suites or asset managers, so it lives outside your existing tooling.
- Model choice takes trial and error. The customization is a strength, but getting the best result often means running the same image through a few models to compare.
