Understanding AI Image Upscaling: How to Enlarge Photos Without Blur

Traditional image upscaling simply stretches pixels, resulting in blurry, pixelated images. AI upscaling is fundamentally different.

How AI Upscaling Works

AI upscaling models are trained on millions of image pairs (low-res and high-res). They learn to:

1. Recognize patterns in low-resolution images

2. Predict missing details that would exist at higher resolution

3. Generate realistic textures and fine details

4. Sharpen edges without creating artifacts

When to Use AI Upscaling

Limitations

Try our Image Upscaler to upscale images 2x or 4x right in your browser.

Before or after upscaling, you may want to crop to exact dimensions - our Image Resizer includes presets for Instagram, LinkedIn, and more.
