Denoise Photo – Clean, Smooth Images
Digital noise ruins otherwise good photos. Those random speckles and grain – especially visible in shadows and even-toned areas – distract from your subject and make images look unprofessional.
What Causes Photo Noise?
High ISO settings: Increasing camera sensitivity to light also increases noise
Low light conditions: Less light means more noise in captured images
Small sensors: Phone cameras and compact cameras show more noise than larger sensors
Long exposures: Extended capture times can introduce noise
Film grain: Analog photographs have inherent grain from film chemistry
Compression: Heavy compression can create noise-like artifacts
How AI Denoising Works
The challenge of denoising is distinguishing noise (random variations to remove) from texture (meaningful variations to preserve). Traditional denoising often destroys both together, creating plasticky, over-smoothed images.
Our AI has learned the difference through training on millions of images. It recognizes that skin has texture, fabric has weave, trees have leaves – and preserves these while removing the random noise overlaid on them. The result is clean images that retain natural texture and detail.
Types of Noise We Remove
Luminance noise: Grayscale speckles affecting brightness – the most common type
Chroma noise: Colored speckles, often visible as red/blue dots in shadows
Film grain: The characteristic texture of analog photographs
Compression artifacts: Blockiness and artifacts from heavy JPEG compression
Sensor noise: Fixed-pattern noise from camera sensor characteristics
When to Denoise
Before upscaling: Noise becomes more visible when images are enlarged. Denoise first for cleaner upscaling.
Before sharpening: Sharpening amplifies noise. Denoise before sharpening for best results.
For old photos: Scanned film photos often have significant grain. Old photo enhancement includes denoising.
For low-light shots: High-ISO and night photos benefit dramatically from denoising.

Frequently Asked Questions
Photo noise has several causes: High ISO settings – increasing camera sensitivity also increases noise; Low light – insufficient light forces higher ISO or longer exposures; Small sensors – phone and compact cameras show more noise than larger sensors; Long exposures – extended capture time allows thermal noise to accumulate; Hot temperatures – warm sensors produce more noise; Aggressive shadow recovery – pushing dark areas reveals underlying noise. Film grain in scanned photos is analogous to digital noise.
Remove noise using AI denoising that distinguishes noise from image detail. Upload your noisy photo, and neural networks trained on millions of examples identify noise patterns while preserving genuine texture and detail. Unlike simple smoothing that blurs everything, AI denoising specifically targets noise while keeping edges sharp, faces detailed, and textures intact. The result is clean photos without the "plastic" look of over-smoothing.
Traditional noise reduction often caused blur because it couldn't distinguish noise from detail, smoothing both together. AI denoising solves this by understanding image content. It recognizes that skin has texture, fabric has weave, and leaves have edges – preserving these while removing only random noise. Modern AI denoising removes grain while maintaining natural texture and sharpness. Some very aggressive denoising might soften slightly, but quality AI maintains detail.
Yes, AI denoising effectively removes film grain from scanned photographs. Film grain is analogous to digital noise – random variations overlaid on image content. The AI distinguishes grain patterns from actual image detail and removes them while preserving photographs' genuine texture and sharpness. You can control the strength of grain removal to completely eliminate grain or reduce it while retaining some film character if preferred.
Apply noise reduction before sharpening and before upscaling for best results. Sharpening amplifies noise, so denoise first. Upscaling makes noise more visible at larger sizes, so denoise beforehand. In a complete workflow: restore damage → denoise → enhance other qualities → sharpen → upscale. If colorizing, denoise before colorization for cleaner color application. Noise reduction early in the workflow benefits all subsequent steps.
