Upscale small images up to 4× without blurring.

How it works

1. 1
   Upload a small or low-resolution image

   The upscaler is designed for images up to 512×512 px — thumbnails, icons, cropped portraits, old scans. Larger images are rejected: resize or crop first.

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.

3. 3
   Download the upscaled result

   The result appears alongside your original for comparison. Download directly — no watermark.

Frequently asked questions

What image sizes does the upscaler accept?

Images up to 512×512 pixels. If your image is larger, crop or resize it to 512px or smaller before uploading. The tool is designed to recover detail in thumbnails, icons, old scans, and other small or low-resolution images.

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. If your image is motion-blurred or heavily compressed, try the Unblur Photo tool first, then upscale.
