What this tool does
Reduce digital noise and grain from your photos in bulk using a median filter. PixelForge's noise reduction tool replaces each pixel with the median value of surrounding pixels, smoothing out random noise while preserving edge detail. Ideal for cleaning up low-light photography, high-ISO camera shots, and scanned images with grain.
Problems it solves
- Cleaning grain from high-ISO photos taken in low-light conditions
- Removing digital noise from a batch of night photography
- Smoothing scanned images with grain or texture artifacts
- Reducing noise before compressing images to prevent compression amplifying artifacts
Example
Apply noise reduction (size 3) to 200 high-ISO event photos
Frequently asked questions
What does the size setting control?
Size controls the radius of the median filter. Size 1 is very subtle. Size 3 (default) gives moderate noise reduction. Size 5–9 gives strong smoothing but may soften fine detail. Start at 3 and increase only if needed.
Will noise reduction blur my images?
A median filter smooths random pixel variations while trying to preserve edges, so it's less destructive than a Gaussian blur. Higher size values will soften fine detail. For heavily noisy images, combine noise reduction with a sharpening pass afterward.
Is this the same as blurring?
No. A median filter replaces each pixel with the median (middle) value of its neighbors, which removes random noise spikes effectively. A Gaussian blur averages all neighbors equally, which also blurs edges. Median filtering is better for noise reduction.
Is this a Pro feature?
Yes — noise reduction is available on Pro and Business plans.
