Download Aiarty Image Enhancer to upscale images, deblur, denoise, and generate details.
Whether it is legacy family photos, web-compressed images, old DVD stills, anime, or AI art, you will find suitable AI models to enhance image quality.
Test 1. Restore details and organic textures
When zooming in on a large screen, the source image becomes blurry and soft. Using the More-Detail model in Aiarty Image Enhancer can enhance quality, restore clear lines, and stay authentic and natural.
Test 2. Fix grainy image and enhance lighting
Low-light Photo
RealPhoto x1 Strength 0.55
Adjust Strength 0.72
Quick Color Correction
For low-light scenes and photos affected by high-ISO sensor noise, the AI models in Aiarty Image Enhancer can distinguish image noise from natural details, reducing noise while preserving organic textures. With the strength slider, you can fine-tune how strongly the AI enhancement is applied.
The comparison images above show the original low-quality photo, Aiarty-enhanced results at different strength levels, and an optional step for quick color correction inside Aiarty.
Test 3. Restore flawed portraits to your specific preferences
Source
Upscale + Restore Face
Optional: Adjust Strength
For low-quality, blurry, or grainy portraits, you can use the Face Enhancer in Aiarty and optionally upscale the image to achieve a balanced, natural-looking result.
In the test above, we applied the MoreDetail model with x4 upscaling and enabled Face Restoration for a faithful recovery. When a larger size and additional detail are needed, the process can be repeated with another x2 upscale.
Test 4. Restore compression artifacts and enhance overall quality
For photos that appear acceptable on smaller screens, compression artifacts such as blockiness often become more noticeable on modern displays or when zooming in. For this kid riding tricycle photo below, his face and hair lacks details, and there are mosquito noise around edges.
To fix the flawed photo, we tested the More-Detail model in Aiarty, upscaling x2, and nudging the enhancement strength around 0.75-0.85, which is a sweet spot for this photo to keep the original feel, while restoring details in face, hair, and fabric textures. Then toggle Face Restoration feature on/off and flexibly adjust color to compare the results with real-time preview.
You can also get more test images and follow the best practices to get the most out of Aiarty.

3. Adobe Photoshop (Firefly)
- Platform: Windows/Mac
- Pricing: $22.99/mo, $275.88/year
- Max Resolution: 4X
- Best for: Professional designers and photographers
Photoshop is a professional design and precise editing tool from Adobe Inc. Now deeply integrated with Firefly Image Model 5, it has evolved from a manual editor into a powerful AI image enhancer among designers, photographers, and advanced hobbyists.
Previously, enhancing images in Photoshop relied on mathematical algorithms like Bicubic or Preserve Details 2.0, which often left images looking soft or artificial. The new Generative Upscale feature changes this by using AI to restore plausible texture and detail onto low-resolution images, effectively restoring photo quality.
Photoshop also now supports third-party models (like Google Gemini and Flux) directly inside the "Generative Fill" tool, allowing users to choose the specific AI model to enhance their images.
For a pictorial guide to enabling generative upscaling or apply manul noise reduction, read about how to upscale image in Photoshop.
Pros

5. Luminar Neo
- Platform: Windows/Mac
- Pricing: $199 One-Time Purchase (1-Year Generative AI Access), or subscription-based
- Best for: Hobbyist photographers and content creators to enhance photos
- Max Resolution: 6X
Luminar Neo is a comprehensive photo editing software developed by Skylum, designed for photographers of all levels. It leverages artificial intelligence to simplify complex editing tasks and enhance images with ease.
The Sky AI feature, for instance, allows users to replace the sky in their images with a variety of options, creating a more compelling and dramatic backdrop; the Magic Light AI tool introduces customizable starbursts around point light sources; and the AI masking feature can analyze and auto creates layers for fine tuning and editing.
There are GenErase to remove objects with deep learning, GenExpand to extend the image and change aspect ratio, Upscale AI for 6x upsizing, and Supersharp AI for picture sharpening. Luminar Neo is more like Jack of all trades, but the lack of focus may result in certain feature being less powerful.
While Luminar Neo is versatile, its broad focus can sometimes mean that certain features aren't as robust. For instance, its noise reduction tool occasionally leaves colored blotches on images, especially those with high ISO settings.
Pros
- AI tools for noise reduction, upscaling, and background removal.
- AI-driven layer masking that automatically detects subjects and creates masks.
- AI powered editing scenarios: sky replacement, AI bokeh, AI lighting, etc.
Cons
- Some AI functions, such as the AI Crop Composition tool and Horizon Alignment, make questionable choices and need refinement.
- The Face Enhancer can produce unnatural results and struggle with smaller faces in the background.
- The realtime previews do not always accurately reflect Luminar Neo's own renderings.
- The perpetual license is pricey compared to more fully-fledged editing apps.

6. Remini AI Image Enhancer
- Platform: Online/iOS/ Android
- Pricing: $179.99/year personal license, no bulk uploads, no commercial usage, enhance up to 20 photos/week
- Max Resolution: 2X, 4X, depending on your mobile chips
- Best for: Beginners looking for on-the-go editing and image enhancement
Remini is a top AI image enhancer, recently ranking high on the App Store. It offers four main improvements: face enhancement, face glow, auto color, and background enhancement, along with old photo restoration.
Remini's approach of photo enhancement also includes retouching, which may change skin tones, alter facial details, and brighten the overall look, as shown in the benchmark testing above.
While it can reconstruct vague shapes in portraits, the results can be hit-or-miss. The latest update allows users to adjust enhancement strength, fixing previous issues of overly strong effects like unnatural facial features.
Pros
- Fix grainy and blurry photos.
- Upscale images and videos.
Cons
- $9.99 weekly subscription is pricey for its features.
- Skin lightening may not suit all users due to ethnicity or personal preferences.
- New models may auto-apply unwanted enhancements.
7. Waifu2X (Online Open-Source)
- Platform: Online
- Pricing: Free, open source
- Max Resolution: 2X, 4X
- Best for: Fix low-quality anime by upscaling with AI algorithms
Waifu2X is a free online image enhancer specializing in 2X or 4X upscaling. It uses a CNN-based model to upscale images without adding extra details. Originally designed for anime upscaling, it also works for photos and digital images, as shown in the testing below.
For this boy portrait, I tested with "medium denoise" in Waifu2X, scale x2. For higher resolutions, it also supports x4 with Tile, TTA and other custom settings. For the denoise option, you need to use it cautiously, as it may have counter effects on noise-free images.
As an online service, it is less stable than standalone software for large file sizes. Also, if you need to batch enhance hundreds of images, Waifu2X is not an ideal option.
Pros
- AI upscaling tech inspired by SRCNN (Image Super-Resolution Using Deep Convolutional Networks).
- Noise reduction to fix compression artifacts.
Cons
- It doesn't have more features to enhance the image except AI upscaling, but there is nothing to complain about since it is free.
- It is less capable of upscaling with details and texture being preserved.

8. Krea AI (Online)
- Platform: Online.
- Pricing: $8~$28/month for 180~900 enhanced images, 4 free enhances for 24 hours
- Best for: Artists and designers who need creative upscaling instead of a faithful enhancement
- Max Resolution: 1x, 2x, 4x, 8x
Krea AI is a powerful photo quality enhancer plus AI image generation and video tools. It's a great free option for creative upscaling, which uses diffusion-based AI to enhance and add creative details to your images.
Besides increasing image resolution, this photo enhancer will also generate details or transfer styles.
For instance, using this benchmark image, when I change the resemblance value from 38% to 85%, the output changes, affecting the boy's facial features, clothing, and surroundings.
You can use prompts to guide the creative upscaling and even negative prompts to specify what you don't want. Krea AI offers various style models like "flat sharp", "strong", "reinterpretation", "oil painting", and "digital art". The chosen model will significantly impact the genre and aesthetics of the final image.
Pros
- Option to adjust AI strength, resemblance, and clarity for creative upscaling.
- Option to use prompts and negative prompts to guide the enhancement.
Cons
- 4K upscaling is not supported in the free plan.
- Since there are many parameters to tweak with, improper value combinations can lead to overfitting.
If you are specifically looking for an image enhancer like Krea AI—a tool that supports style transfer and creative upscaling—free options include Stable Diffusion (for style transfer and upscaling) and the Clarity Upscale workflow. A paid alternative is Magnific AI.
9. chaiNNer (Open-Source GUI)
- Platform: Windows, Mac, Linux
- Pricing: Free open-source
- Best for: Geeks familiar with node-based image processing workflow
- Max Resolution: 16K/32K
ChaiNNer is a GUI-based tool for image enhancement, upscaling, restoration, and processing. It requires technical setup, including installing dependencies like PyTorch (~2GB), NCNN, and ONNX, as well as photo enhancer models, before connecting nodes to build workflows.
My Tests: As shown in the portrait photo, two models produce different results. While both reduce blockiness and enhance details, Seedvr2 reconstructs fabric textures, whereas Nano Banana interprets the tiny black spot as a mole on the face.
You can also find free open-source AI upscaling models on OpenModelDB and implement them into the ChaiNNer workflow. Such as:
- For image upscaling: SwinIR-L model at https://github.com/JingyunLiang/SwinIR
- For face restoration: CodeFormer model at https://github.com/sczhou/CodeFormer
Note: Since chaiNNer is only a GUI, not the models themselves, we won't list the pros and cons here. The output image quality depends on which model you installed and how you apply it in the workflow.
10. Let's Enhance (Online)

You can also switch among Gentle, Balanced, Magic and other models, as it comes down to personal preferences for fidelity or creative upscaling. It also includes Light AI, tone, and color enhancer.
Pros
- Light AI, tone AI, upscaler and background remover.
Cons
- For smaller faces that occupy only a tiny portion of the image, this online enhancer often fails to enhance them with sufficient detail.
- The enhanced images sometimes turn out less saturated than the original images.
- The free plan puts a watermark on enhanced images.
