FAQ
Is Upscayl free?
The Upscayl desktop client is completely free and open source, with no usage limits or watermarks. If you need higher extreme resolutions or lack a compatible GPU, you can also opt for its paid cloud service, Upscayl Cloud.
What can Upscayl be used for?
Upscayl is mainly used to losslessly enlarge and enhance low-resolution, blurry, or pixelated images. It's great for restoring old photos, enlarging digital artwork, or improving the clarity of low-quality web assets.
What hardware does the Upscayl desktop version require?
Since Upscayl desktop performs all computation locally, it needs a Vulkan-compatible graphics card (GPU) to work properly. Without a dedicated GPU or with an older one, processing may be slow or may not run at all.
How is Upscayl different from Magnific AI?
Upscayl focuses on faithful, lossless sharpening and denoising that stays true to the original and never fabricates details, and the desktop version is completely free; Magnific AI is a generative upscaler that uses AI to create new realistic textures (like skin pores) and is quite expensive.
Can Upscayl batch process images?
Yes. Upscayl offers an extremely friendly batch processing feature: just import multiple images or select an entire folder, and all images are automatically upscaled in one go, greatly improving efficiency.
Will Upscayl leak my personal image privacy?
When processing images with Upscayl desktop, all computation happens entirely on your own local computer with nothing uploaded to any server, so your image data and privacy are 100% safe.
