6 Best AI Image Upscalers Tested for Natural Photo Enlargement

PetaPixel tested six AI-powered image upscalers—Aiarty Image Enhancer, Topaz Gigapixel AI, Upscayl, Adobe Super Resolution, ON1 Resize AI, and Let's Enhance—focusing on fidelity and natural-looking results. The review emphasizes that modern upscalers can enlarge photos to 4K or 8K, but preserving original texture and avoiding an artificial 'plastic look' remains the key challenge. Aiarty Image Enhancer, the sponsored tool, was tested on wildlife, low-light portraits, low-resolution landscapes, and commercial photos. It offers adjustable strength, face restoration, batch processing, and supports RAW files. Other tools are compared: Topaz Gigapixel AI for high-end detail, Upscayl as a free open-source option, Adobe Super Resolution for RAW workflows, ON1 Resize AI for large-format prints, and Let's Enhance for cloud-based convenience. Aiarty is currently offering a 49% discount on its Lifetime License ($79, down from $155). The article concludes that the best choice depends on the photographer's workflow and output needs.
