Use it every day
Honestly didn't expect to like it this much. Optional online version is exactly what I needed, and runs locally for privacy. I do wish results vary by image and model, but I reach for it almost every day now and it just clicks.
Years in this space
I've evaluated a lot of these over the years. What stands out here is optional online version — handled better than most — and batch processing available. GPU recommended for good speed is my one real gripe. Worth the time if this is your use case.

Compared a few options
Evaluated this against two competitors. Where it wins: multiple upscaling models and free and open source. On balance the feature set — especially cross-platform desktop app — justifies the 5 stars for our use case.
问答
How much does Upscayl cost and is it really free to use?
Upscayl is completely free and open source. You can download the desktop app or use the optional online version without paying, with no subscription or upload-based pricing tiers mentioned.
What types of images does Upscayl handle best, and are there limits?
Upscayl offers multiple AI models tuned for different content like photographs, digital art, and illustrations, and supports batch processing up to 16x. However, results vary by image and model, and it offers limited editing features beyond upscaling itself.
What hardware do I need to run Upscayl effectively?
Upscayl runs locally on supported cross-platform desktop systems, and a GPU is recommended for good processing speed. Without a capable GPU, upscaling will still work but can be noticeably slower, especially for batch jobs or high scale factors like 16x.
