Low-resolution, soft originals upscaled to crisp 4K/6K/8K. The AI rebuilds fine detail — skin texture, hair, fabric weave, edges — and automatically sharpens faces, so the result looks naturally high-resolution, not over-sharpened.
A small, soft selfie upscaled to 4K. Faces are auto-detected and enhanced, recovering eye, skin, and hair detail without a plastic look.

AI Resultsparkpix.ai is a free, browser-based AI photo upscaler that enlarges images to 4K, 6K, or 8K and automatically enhances faces — no download, and no signup for your first result, which is ready in 5–30 seconds. Your first upscale each day is free without an account (2 per day with a free account; 3 credits per image beyond that). It rebuilds real detail with a super-resolution neural network instead of stretching pixels, so edges and textures stay sharp. Best for low-resolution portraits, pixelated product shots, and small old scans you want to print or display large.
