Image Upscaler

Make a small image larger, right in your browser. This tool enlarges your image with canvas interpolation. It does not use AI and cannot invent detail that was not in the original, so a very blurry original will still look soft when enlarged. Your image never leaves this page.

How to use it

  1. Upload a small image, or try the sample image.
  2. Pick 2X or 4X and your edge style.
  3. Click “Upscale image,” then download the PNG or JPG.

Best for: small logos, thumbnails, and graphics that need to meet a minimum size. Not a fix for a badly blurred photo. Read the guide: How to upscale a low-resolution image without blur.

Limit: output is capped at 4096 px on the longest side so large images do not freeze the browser.
