Upscale small images up to 4× without blurring.

How it works

1. 1
   Upload any image

   Works on thumbnails, icons, cropped portraits, and old scans — those gain the most, with real detail recovery rather than blur. Larger photos are cleaned up and sharpened at a bounded output size.

2. 2
   Pick your scale factor

   2× doubles each side (so a 256×256 thumbnail becomes 512×512). 4× quadruples it (256×256 → 1024×1024). Both modes recover detail, not just bilinear stretch.

Frequently asked questions

What image sizes does the upscaler accept?

It works best on small or low-resolution images — thumbnails, icons, old scans — where it recovers real detail. Everyday photos are accepted too and downscaled to a bounded working size (output tops out around 2048×2048 px). Very large files — over 25 MB or very high resolution — are refused; resize those first.

What is the difference between 2× and 4× upscaling?

2× doubles each side of your image. 4× quadruples it. Both use AI to reconstruct fine detail rather than blurring. 4× takes a little longer and produces a much larger file — use it when you need maximum enlargement.

Will it sharpen my blurry image?

Upscaling and sharpening are related but different. Upscaling enlarges the image while recovering expected detail; it does not undo motion blur or heavy compression.
