About Image Upscaler

Image Upscaler enlarges small pictures 2x, 3x or 4x using high-quality resampling and smart sharpening, so they look cleaner than a simple stretch when printed or shown on large screens.

Good to know

This is mathematical upscaling, not AI; it can't invent detail that isn't there, but it greatly reduces blockiness. This is a Pro tool.

How to use Image Upscaler

  1. Upload an image (JPG, PNG, WEBP; HEIC on the HEIC tool).
  2. Change the settings — the preview updates as you go.
  3. Compare before and after, zoom in to check details, and use Reset if needed.
  4. Choose the output format and download.
