About the Image Upscaler

Small or low-resolution images look blurry when printed or used as a banner. The upscaler enlarges a picture 2×, 3× or 4× in gradual steps and then applies an adjustable sharpening pass, which keeps edges crisper than a single big stretch.

When to use it

  • Making an old or small photo large enough to print
  • Enlarging a logo for a banner or presentation slide
  • Improving tiny product images supplied by a manufacturer
  • Preparing artwork for a higher-resolution screen

Tips for the best results

  • Start with a sharpening level around 0.5 — too much creates halos around edges
  • 2× gives the most natural result; 4× is best for graphics and illustrations
  • Upscaling can’t recover detail that was never captured, but it removes visible pixelation

How to use the Image Upscaler

  1. Open the Image Upscaler and drop your image (or tap to choose one).
  2. Adjust the options — the preview updates instantly.
  3. Press Download to save the result. Nothing is uploaded.
