AI upscaler

Upscale and enhance images with AI, free and private.

This AI image upscaler increases the resolution of your photos by 2x or 4x, sharpens soft edges, and cleans up blur, all inside your browser. Your images never get uploaded, so they stay on your device. No signup, no subscription, and no watermark on what you download.

  • Runs on your GPU
  • 2x or 4x

Why use this

Fast, private, and free.

  • Upscale any photo 2x or 4x with a Real-ESRGAN style AI model that adds real detail, not a blurry stretch
  • Sharpen soft focus and reduce blur to make faces, text, and textures clearer
  • Runs entirely in your browser on your GPU, so nothing is uploaded and there are no file count or size limits
  • Export the enhanced result as PNG, JPEG, or WebP, with a hold-to-compare against the original
How it works

Three steps, all on your device.

  1. 01

    Drop your image

    Drag a JPG, PNG, or WebP into the tool or browse to pick one. On the first run the AI model downloads once and is cached in your browser for next time.

  2. 02

    Pick 2x or 4x

    Choose how much to enlarge. The model runs on your GPU, adding detail and sharpening blur as it increases the resolution.

  3. 03

    Compare and download

    Hold Compare to check the result against the original, then download it as PNG, JPEG, or WebP. Nothing was uploaded at any point.

FAQ

Good to know.

Is this AI image upscaler free?
Yes, the Pixasur AI image upscaler is completely free with no signup, no subscription, and no watermark on your results. You can upscale as many images as you want because the work runs on your own device.
How much can I upscale an image?
The Pixasur AI image upscaler enlarges images by 2x or 4x, so a 1000 by 1000 pixel photo becomes up to 4000 by 4000 pixels. It uses an AI super-resolution model to add detail rather than simply stretching the pixels, which keeps edges and textures sharp.
Are my images uploaded to a server?
No, the Pixasur AI image upscaler runs entirely in your browser and your images never leave your device. The AI model downloads once to your browser and then all processing happens locally on your GPU, so nothing is sent over the network.
Can it unblur or enhance a low quality photo?
Yes, the Pixasur AI image upscaler sharpens soft focus and reduces blur while it increases resolution, which makes faces, text, and fine detail clearer. It adds plausible detail with AI, so it improves most photos, though it cannot invent information that was never captured in a heavily blurred source.
Do I need a special browser or graphics card?
The Pixasur AI image upscaler runs fastest in a browser with WebGPU support such as recent Chrome or Edge, using your device's GPU. If WebGPU is not available it falls back to a slower path so you still get an upscaled result, and the first run downloads the AI model once and caches it for next time.
What image formats does it support?
The Pixasur AI image upscaler reads JPG, PNG, and WebP images and lets you download the enhanced result as PNG, JPEG, or WebP. PNG is best for text and graphics, while JPEG or WebP keep photo files smaller.
