About this tool
- 1
Upload a noisy photo
Select a photo with visible grain, speckle, or digital noise - often from low-light shooting.
- 2
Select denoising strength
Choose light, medium, or heavy noise reduction depending on how noisy the image is.
- 3
Preview the result
Compare the denoised version against the original to check detail preservation.

Save the denoised image at full resolution.
- Use the lightest effective setting - aggressive denoising can make photos look artificially smooth.
- Zoom to 100% to evaluate detail preservation, especially on textures like skin, hair, and fabric.
- Photos shot at high ISO (1600+) benefit the most from denoising.
- Apply denoising before other edits like sharpening to avoid amplifying noise.
- AI-powered noise reduction
- Multiple strength levels
- Detail preservation mode
- Before/after comparison
- Handles both luminance and color noise
- Clean up low-light and nighttime photography shot at high ISO.
- Restore old scanned photos with visible film grain or scanner noise.
- Improve video call screenshots and webcam captures.
- Prepare noisy surveillance or security camera stills for clearer viewing.
Digital noise comes from the camera sensor amplifying the signal in low light (high ISO). It appears as random colored speckles or grainy texture, especially in shadow areas.
Some detail loss is inevitable with noise reduction. The AI model is trained to distinguish noise from detail, but aggressive settings can smooth out fine textures. Use the lowest effective strength.
