Best 9 Noise Reduction Software for Denoising Images

In the realm of photography, few things are more disconcerting than capturing the perfect shot, only to later discover it's marred by the unwanted guest known as 'image noise'.

These common irritants manifest as random variations of brightness or color information in images, often due to electronic noise produced by the camera's sensor. Image noise is the digital equivalent of grain in film photography and while sometimes artists use it to add a certain aesthetic appeal to their photos, more often than not, it can degrade image quality, especially in low-light conditions.

Luckily, with the advent of tech solutions, we now have image noise reduction software at our disposal. Harnessing sophisticated algorithms, they can miraculously transform our noisy image into a much cleaner and visually pleasing photograph.

Here, I've tested dozens of denoise software and picked the 9 best ones for your choices to denoise your images and photos efficiently. 8 of them are AI denoiser, so you can remove grain and noise with minimal effort.

Let's take a closer look at each of them.

Adobe Lightroom Classic is a desktop photo editor that allows us to enhance photos by adjusting colors, enhancing blurry images, removing unwanted elements, straightening crooked shots, and more.

In addition, it provides 2 simple methods to reduce noise in images. In the Develop module, we can use the conventional approach to reduce luminance and chromatic noise. If we have Lightroom 6.3 or a later version, we can utilize the AI denoise to eliminate noise from RAW images automatically while preserving most details.

Testing with Adobe Lightroom Classic

Note: The AI denoise feature has garnered positive feedback from photographers. However, it is limited to working only on images in Bayer Mosaic format, making it unable to remove noise from JPEG, PNG, and other common formats.

Test Result – Image 1

The Lightroom noise reduction tool effectively removes noise from the image, but the downside is a noticeable loss in detail, resulting in a somewhat smudged appearance.

Test Result - Image 2

The outcome is a mesmerizing buttery texture in the foreground, reminiscent of a skillfully painted portrait rather than a conventional photograph.

3. Topaz Photo AI

Best for advanced users to sharpen and reduce image noises on top-of-the-line PCs.

• Rating: 4/5 by PCMag
• Supported image formats: JPEG, BMP, PNG, GIF, TIFF...
• Platforms: Windows 10/11, macOS Big Sur 11 and higher
• Pricing: $199 (one-time purchase with only one year of upgrades)

Topaz Photo AI stands out as an intelligent three-in-one image enhancer, harnessing deep learning technology to eliminate noise, enhance sharpness, and boost resolution.

According to the developers at Topaz Labs, the denoise feature is powered by deep-learning algorithms that can differentiate between noise and crucial image details. This allows users to effectively reduce unwanted graininess and artifacts while preserving the essential textures and fine details that are often lost with traditional noise reduction tools.

Testing with Topaz Photo AI

Test Result – Image 1

The details in both the background and the main subject have been well-preserved.

Upon closer examination, I found that the feature appears to be overly sharpened. The feather in the original image has a soft and delicate appearance, whereas, in the denoised image, it appears rigid and rough.

Test Result - Image 2

It effectively removes almost all perceivable noise while maintaining only a slight, subtle smudging effect.

Let's zoom in. We can find the details in the eyes, individual strands of hair, facial shadows, and skin creases are remarkably retained. However, in comparison to Aiarty Image Enhancer, Topaz Photo AI loses some detail in the fingers and knuckles. Overall image clarity is slightly inferior to Aiarty Image Enhancer as well.

4. DxOPhotoLab

Best for advanced users to reduce noise from RAW images on top-tier PCs.

• Rating: 4/5 by PCMag
• Supported image formats: RAW, native DNG from supported cameras, Linear DNG from supported cameras, Linear DNG from DxO PhotoLab, JPEG, PNG...
• Platforms: Windows 10/11 (version 20H2, 64-bit) or later, macOS 12.6.8 (Monterey) or later
• Pricing: $229 (one-time purchase)

DxO PhotoLab is a great tool for people who want to edit their RAW photos. It lets us convert, retouch, and edit photos in RAW format.

In the DxO PhotoLab 4 and 5 ELITE Edition, we get 3 ways to reduce digital noise: HQ (High Quality), PRIME, and DeepPRIME. The HQ method is good for simple situations and is the default choice. It works quickly and shows us a full preview before saving our final image. The other 2 methods are more advanced but can only be used with RAW files.

Testing with DxOPhotoLab

Test Result – Image 1

The result was an improvement over Lightroom, but it was challenging to reduce noise without making the image too soft. Additionally, a strange green edge was visible on the right side of the bird, and the bird's color appeared different from the original.

Test Result - Image 2

The image still appears noisy and low in quality, with faces and clothing looking overly soft and smudged. Additionally, the color of the denoised image appears warmer and brighter compared to the original.

5. Neat Image

Best noise reduction plugin for Adobe Lightroom and Adobe Premiere Pro.

• Rating: 4.3/5 by PCMag
• Supported image formats: JPG, TIF, PNG, and BMP

Neat Image, true to its name, is a specialized tool for enhancing our images by reducing various imperfections such as luminance noise, dust, motion blur, film grain, JPEG artifacts, and other common issues.

In addition to functioning as an image denoise plugin for photo editing programs, Neat Image is also offered as a standalone program compatible with major operating systems.

Testing with Neat Image

Test Result – Image 1

While Neat Image does a good job of cleaning up the noise and graininess in the background pixels, it seems to have over-smoothed the details of the bird in the foreground. Rather than capturing the intricate textures and individual feathers, the bird now has a painted, almost illustrative appearance, lacking the natural, lifelike quality of the original.

Test Result - Image 2

The denoised image appears over-processed, resembling digital art. The hair appears excessively blurred. Facial features seem painted on, lacking the texture of real skin. The earrings look like odd, solid-colored lines. The patterns on the clothes are nearly erased, appearing as a jumble of white pixels stacked together.

6. Fotor

Best for beginners to sharpen and reduce image noises directly on the browser.

• Rating: 4/5 by CaptureLandScape
• Supported image formats: PNG, JPG, and SVG
• Platforms: Windows, Mac, Android, iPhone, etc
• Pricing: $89.88/year with 300 credits for generative AI ($19.99/month for Fotor Pro+)

The image denoise function in Fotor is user-friendly, with two sliders—one for adjusting luminance noise and the other for color noise.

Testing with Fotor

Test Result – Image 1

Increasing the denoise level results in a smeared appearance and loss of important details, while decreasing it can leave unwanted noise in the image. Below is the best result I can get with Fotor. However, the overall appearance is excessively softened and lacks sharpness.

Test Result - Image 2

The image still looks noisy and low quality even though I pull the slider of luminance and color noise slider to the maximum.

7. Nero AI Image Denoiser

Best for beginners to denoise slightly noisy images that come in small sizes.

• Rating: 3/5 by Slashdot
• Supported image formats: PNG, JPG, and SVG

Nero AI presents a suite of AI-powered tools accessible directly through our browser, featuring capabilities like photo restoration, colorization, and avatar generation.

Among its offerings is the AI Image Denoiser, designed to enhance noisy images with ease by just uploading the original image. Notably, the denoising process is fully automated, making it user-friendly for beginners. However, the lack of customization options means that if the resulting image is unsatisfactory, there are no avenues available to refine it.

Testing with Nero AI Image Denoiser

Test Result – Image 1

The background now appears sharp and clear. However, the bird's feather has turned into a blurry mass resembling felt, lacking the expected texture and detail.

Test Result - Image 2

When viewed at a smaller scale, the effect seems quite good - the noise has been completely removed, and the person's skin still retains a reasonable amount of detail.

However, when zooming in to 50% or more, the skin appears waxy and has lost much of the natural texture and fine details that would be expected.

8. AVCLabs Photo AI

Best for enhancing the quality of a single grainy photo.

• Rating: 3.5/5 by G2
• Supported image formats: JPG, PNG, BMP, JFIF, and WebP
• Platforms: Windows 11, 10(64bit); macOS 10.15 and above

AVCLabs Photo AI uses advanced deep learning technology to enhance images by increasing their size by 200%, 300%, and even up to 400%. This process sharpens and cleans up images, delivering clear results while preserving the original content.

AVCLabs highlights that its denoising feature, powered by a fast and adaptable convolutional neural network, effectively eliminates noise from images while accurately restoring fine details.

Testing with Nero AI Image Denoiser

Test Result – Image 1

It seems AVCLabs Photo AI did fix the image noise. Sadly, the loss of detail in the feather and the texture of the tree trunk is apparent even when viewing the denoised image at a smaller size, not just in the larger original version.

Test Result - Image 2

At first glance, the denoised image appears satisfactory, with most of the intricate hair details preserved.

However, upon closer magnification, a faint smearing or artificial smoothing becomes perceptible, especially when examining the details of the lips, eyes, and brows.

9. HitPaw Photo Enhancer

Best for eliminating image noise while enhancing facial details.

• Rating: 2/5 by G2
• Supported image formats: JPG, JPEG, PNG, and WebP
• Platforms: Windows and Mac
• Pricing: $90.39/year with 500 credits

The HitPaw Photo Enhancer is another decent piece of image enhancer that uses AI to make our images look better. Its General Denoise model can help reduce unnecessary noise and sharpen details in our photos automatically.

Plus, this photo noise reduction software has a Face Model, with which we can restore blurry faces. Anime lovers will appreciate the Animation Model - this boosts resolution to enhance our viewing experience. And if we have black and white videos, the Colorize Model will add vibrant colors to them, making them look more real.

Testing with HitPaw Photo Enhancer

Test Result – Image 1

The denoised image looks very similar to, or even worse than, what I got from the denoise feature of AVCLabs Photo AI. While there's no noticeable noise remaining, the fine details of the feathers have been over-smoothed, leaving them looking smudged and unclear.

Test Result - Image 2

The effect is somewhat average, better than Neat Image and Fotor but not as good as Topaz and Aiarty Image Enhancer.

It was somewhat disappointing in terms of preserving fine details. On a close look, we can find the facial features have become blurry and almost plastic-looking.
