Crystal Upscaler is a high-resolution image-enhancement model developed by Clarity AI, known for building advanced upscaling and restoration tools. The model is designed to increase image resolution dramatically while maintaining sharp details, clean edges, natural textures, and accurate skin tones. It can be used for portraits, product photos, artwork, and any imagery that needs high-fidelity enlargement.
The hosted version of Crystal Upscaler is available on the fal.ai platform, where users can upload an image and receive an enhanced, higher-resolution output. The service supports common image formats such as JPG, PNG, WebP, GIF, and AVIF. Clarity AI and community posts have highlighted recent upgrades allowing output up to roughly 14K-class dimensions, with the capability to generate images in the ~200-megapixel range, though exact maximum dimensions may vary depending on settings.
For developers and those interested in local experimentation, an older open-source implementation exists under the AGPL-3.0 licence on GitHub, maintained by the same developer behind the service.
Crystal Upscaler is positioned as a tool for photographers, designers, archivists, and creators who require extremely high-resolution outputs with as much structural fidelity as possible.
