Median Pass Filter

Apply median pass filter to remove noise while preserving edges with multiple algorithms

Image File *

Click to upload file or drag and drop file here

Maximum file size: 20MB Supported formats: image/jpeg, image/png, image/webp, image/gif, image/bmp, image/tiff

Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to remove noise while preserving edges

Median Algorithm

Choose median filter algorithm. Standard works well for most noise types

Kernel Size

3 3 25

Size of the median filter kernel (must be odd). Larger kernels remove more noise but may blur details

Filter Iterations

Number of median filter passes. More iterations = stronger noise reduction

Noise Threshold

0 30 255

Sensitivity for noise detection. Higher values filter less aggressively

Preserve Edges

Maintain edge detail while removing noise

Channel Processing

Choose which color channels to process

Output Format

Choose output format or keep original. PNG recommended for maximum quality

Quality (1-100)

Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size
