Denoising Tips
Start with moderate settings and gradually increase strength. Use edge preservation for photos with fine details. For old photos, try salt & pepper noise removal first.
About Image Denoise Tool
The Image Denoise Tool is a powerful online solution for removing noise and grain from digital images. Using advanced filtering algorithms, this tool effectively reduces Gaussian noise, salt-and-pepper noise, and other image artifacts while preserving important details and edges. This free image denoising tool works entirely in your browser, providing secure and private noise reduction without uploading files to external servers.
Image noise reduction involves sophisticated mathematical algorithms including Gaussian filtering, median filtering, and edge-preserving techniques. These methods are fundamental in digital signal processing and computer vision. Learn more about the technical foundations of noise reduction in the comprehensive Wikipedia article on Noise Reduction, which covers various algorithms and applications in digital image processing.
How to Use This Tool
- 1 Upload your noisy image by clicking "Choose File" or dragging it into the upload area
- 2 Select the noise type: Gaussian for general noise or Salt & Pepper for speckle noise
- 3 Adjust the denoising strength and detail preservation settings using the sliders
- 4 Enable "Preserve Edges" to maintain sharp details while removing noise

Frequently Asked Questions
- What types of noise can this tool remove?
- Our tool effectively removes Gaussian noise (common in digital photos), salt-and-pepper noise (random black and white pixels), and general image grain from various sources including low-light photography and scanner artifacts.
- Will denoising make my image blurry?
- Our advanced algorithms are designed to remove noise while preserving important details. Use the "Preserve Edges" option and adjust the detail preservation slider to maintain sharpness in important areas.
- What's the difference between Gaussian and Salt & Pepper noise removal?
- Gaussian noise removal uses smoothing filters for general noise reduction, while Salt & Pepper mode uses median filtering specifically designed for random pixel artifacts and speckle noise.
- How should I adjust the strength settings?
- Start with moderate strength (around 50%) and gradually increase if needed. Higher strength removes more noise but may soften details. Use the detail preservation slider to balance noise removal with image sharpness.
- Can I denoise old or scanned photos?
- Yes! This tool is excellent for cleaning up old photos, scanned documents, and vintage images. Try the Salt & Pepper mode first for speckle noise, then Gaussian mode for general grain reduction.
