Best 3 AI Image Denoiser [One Free] to Denoise Image on PC, Mac, Photoshop, and Online

When taking pictures at night, or there isn’t enough light, or the camera isn’t set up right, there can be too much noise in the photo. Noise can ruin your photography. So, how do you denoise images?

Adobe Lightroom Classic is the most widely used photo editing program to edit photos and do image noise removal. It’s the top program, and there is currently no serious competitor in terms of image editing or image management. Even though Lightroom Classic has a lot of options, I don’t quite like the image noise reduction function. I always thought there must be a better way.

In this situation, some of my friends told me that there are AI image denoisers that do a great job in noise reduction. In this post, I’d like to recommend 3 AI-based programs to denoise images on your PC, Mac, or online.

What is an AI Image Denoiser and Why Do You Need It?

Images often contain unwanted noise that can be introduced from various sources like low light, high ISO settings, or older sensors. Noise appears as graininess, blurriness, or pixelation in photos and reduces quality by impacting sharpness, contrast, colors, and visibility of details.

An AI image denoiser is a tool that uses machine learning algorithms to detect and remove noise from images. It analyzes photos to distinguish between actual details and random noise patterns. By eliminating noise, AI denoising produces cleaner, sharper, and more natural looking photos.


You may need an AI denoiser if you frequently take pictures in noise-prone situations. For example, indoor or night scenes often have low light that increases noise. High ISO settings, long exposures, or older cameras can also contribute to noise. An AI denoiser can help improve the quality of photos from these challenging lighting conditions or equipment.

How to Choose the Best AI Image Denoiser

When selecting a denoising tool, consider factors like algorithms, presets, controls, masks, features, performance, usability, compatibility, and price.

Algorithms affect how noise is identified and removed. Presets offer automated settings while controls allow custom fine-tuning. Masks target specific areas. Features provide additional editing options. Performance impacts speed and resource usage. Usability revolves around the interface and learning curve. Compatibility involves file support and platforms. Price determines value and affordability.

Evaluate these qualities across different options. Look for reviews from reputable sources and compare strengths versus needs. Demo or trial versions help you test functionality. The best denoiser balances all criteria for your specific workflow and photography style. With the right tool, AI can enhance image quality by intelligently eliminating distracting noise.
