Denoise images
Smooth the grain and coloured speckles from night, concert and indoor photos while keeping edges crisp. Instant on your device, with an AI denoise for the worst cases.
Open a photo to get instant, private fixes in your browser, then optionally run an AI pass.
What noise reduction actually does
High ISO noise has two parts: grainy brightness speckles (luminance noise) and red/green/blue blotches (colour noise). Your eye forgives the first far more than the second.
Less noise at the moment you shoot
- Add light before anything else: move towards a window or lamp.
- Expose properly. Brightening a dark photo afterwards lifts the noise with it. Tap on the subject so the phone exposes for it.
- Use night mode and hold still: it merges many frames, which averages away noise.
- Avoid digital zoom, which enlarges noise along with the subject.
Questions people ask
What causes noise in photos?
Too little light. The sensor records fewer photons, the camera amplifies the signal (a higher ISO), and random variation between pixels becomes visible as grain and coloured blotches. Small phone sensors in dim rooms and night scenes show it most.
How do I remove noise without losing detail?
Use the smallest noise reduction that makes the grain acceptable, not invisible. This tool smooths colour noise strongly and brightness noise gently, and stops at edges. Add a little Sharpen afterwards to bring back texture.
Should I denoise before or after sharpening?
Before. Sharpening amplifies noise, so it always comes after noise reduction. This tool applies them in that order automatically.
When should I use AI denoise?
For very noisy night shots where the instant filter turns everything waxy. The AI pass rebuilds texture that the noise hid. It can soften fine repetitive detail like distant foliage, so compare before saving.
