IMAGE_UPSCALER

Drop in a PNG, JPG or WEBP, pick a size and a preset, compare before and after, download. Your image never leaves the browser.

NO_IMAGE_YET

Load an image on the left and the upscaled preview shows up here, with a slider to compare it against the original.

HOW_IT_WORKS

  • The image is enlarged in 2x steps with the browser's high-quality smoothing, then resized to your exact target
  • Sharpen, contrast, saturation and brightness are applied pixel by pixel on a canvas
  • Everything runs on your device: the image is never uploaded anywhere
  • 8x on a big photo needs a lot of memory, so keep an eye on the readout before you hit apply
