Image Noise Remover - Fix Grainy Photos in Your Browser

Low light, high ISO, cheap camera, old scan, over-compressed JPEG - the result is the same: grainy, noisy, ugly photos that look great as art and terrible everywhere else. The professional fix is dedicated denoising software like DxO PureRAW or Topaz Denoise AI, both of which cost $80–$200 and require a desktop install. OptiPix's free Image Noise Remover runs a non-local means denoising algorithm in your browser, no install, no upload, no signup.

What makes OptiPix's Noise Remover different

Most online "noise reducers" run a simple Gaussian blur that destroys detail along with the noise. Real denoising preserves edges by comparing patches across the image and averaging only similar ones. OptiPix uses that approach client-side.

Key features

Who is it for

For grainy old photos that need more than just denoising, our Photo Restoration tool fixes scratches, fading, and yellowing in addition to noise. And if your photo is small to begin with, our Image Upscaler can enlarge it 2× or 4× while denoising in the same pass.
