Image Noise Remover
Reduces noise in photos using a median filter — which removes salt-and-pepper speckles while preserving edges — or a gentle smoothing blur for uniform grain, with adjustable strength and instant before/after preview.

Notes
- Median filtering replaces each pixel with the median of its neighborhood: extreme outlier pixels (the speckles) vanish, real edges mostly survive.
- Denoising always trades a little fine detail for smoothness — zoom in on the preview before downloading.
- Everything runs locally in your browser; your images are never uploaded to any server.
