Reduce an image's noise

Reduce noise and grain in an image with AI, keeping its original size, directly in your browser.

Processed on your device via WebAssembly. Nothing is sent to any server.

or click to select it

Uses a photo restoration model (Real-ESRGAN, compact variant) running in your browser via WebAssembly: it first reconstructs the image at higher resolution while smoothing noise and artifacts, then scales it back down to the original size — a known technique for cleaning up a photo without enlarging it.

Use cases

  • Cleaning up grain in a low-light photo.
  • Reducing noise in a scanned image.
  • Smoothing compression artifacts in a heavily compressed photo.

How it works

  1. 1

    Upload the image

    Low-light photos usually have more noise to clean up.

  2. 2

    Click "Enhance"

    The first time it downloads an AI model (~5 MB).

  3. 3

    Download the result

    Same size as the original image, but cleaner.

Frequently asked questions

Does the result lose detail?

The model balances cleaning up noise with preserving real detail; in very noisy areas, some smoothing is unavoidable.

Why does it use a super-resolution model to reduce noise?

It's the same technology: the model reconstructs a clean image at higher resolution and then scales it back to the original size, taking advantage of how that process naturally smooths out noise.
