You might not realize it, but an image denoiser is one of the most essential photo editing and noise reduction tools. It is used for image noise reduction and to remove any unwanted graininess. An image with too much noise is not pleasing to a customer’s eye or for your potential clients and audience. Unlike an image upscaler that make small photos larger while retaining their quality, image denoisers focus on reducing noise and artifacts in images to make them look better.

What is image noise reduction?

First of all, it’s crucial to understand the meaning of denoising or noise reduction. When a photo is shot in less-than-optimum light conditions, the pixels in the photo become visible, leading to a “noisy” image compared to a smooth one. When you employ Denoise AI tools, the quality of an image is restored and enhanced by getting rid of the grainy texture in the photo.
