Frequently Asked Questions

What types of noise can this remove?

The AI handles luminance noise (grain), chroma noise (color speckles), and JPEG compression artifacts. It works on both subtle noise and heavily grainy images.

Will denoising make my photo blurry?

Our AI is trained to distinguish between noise and real detail. It removes noise while preserving edges, textures, and fine details like hair and fabric patterns.

Does this work on smartphone photos?

Yes. Smartphone cameras often produce noisy images in indoor and low-light conditions. This tool is ideal for cleaning up phone photos.

Can I adjust the denoising strength?

Yes. Use the intensity slider to control how aggressively noise is removed. Lower settings preserve more original detail; higher settings produce cleaner results.
