AI Image Upscaler — Enhance Any Image to 4K
Upload a low-resolution image and let AI upscale it to HD or 4K. Sharpen details, reduce noise, and enhance clarity without losing the original look. Perfect for old photos, screenshots, and web images.
How It Works
1. Upload Your Image
Select any low-resolution image. Works with photos, screenshots, artwork, game captures, and more. We accept PNG, JPG, and WebP.
2. Choose Your Scale
2x HD doubles your resolution. A 720p image becomes 1440p. Great for social media and web use. Free tier.
4x 4K quadruples resolution using our Pro model. A 1080p image becomes true 4K. Ideal for printing and large displays.
3. Download Your Enhanced Image
Get a crisp, detailed image with AI-enhanced sharpness, reduced noise, and clean edges. No manual tweaking needed.
