Download Aiarty Image Enhancer to upscale images, deblur, denoise, and restore natural details.
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 helps 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
While a photo can appear acceptable on a smaller screen, 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.
AI-Powered Enhancing Tech in Aiarty:
Aiarty Image Enhancer has essential AI models to enhance image quality: More-Detail V3 for AI art and any picture that needs natural details after upscaling; AIGC Smooth V3 for clarity and smoother results and Real Photo V3 for faithful photo restoration, such as pixelated, blurry, soft, and noisy images.
Highlighted Features:

- Max Resolution: 1x, 2x, 4x or Max.
- Best for: Photographers with powerful computers to restore and enlarge images without losing quality.
Topaz Photo is another frequently recommended AI image enhancer, both by content creators and in Reddit communities. You can upscale, sharpen and denoise photos with Topaz, or use the lens correction feature to fix blurry pictures. It also upscales low-res images up to 600%, with outputs in DNG, JPEG, PNG, or TIFF.
However, its pricing can be a deal-breaker for some users, especially since Topaz Labs switched to a subscription model in September 2025.
Testing Topaz: For the same kid portrait as the benchmark, Topaz works to bring back clarity to the blocky area, with a saturated look and hair details. You can adjust parameters to fix compression and remove blur.
Pros
- Auto face detection and restoration.
- Autopilot feature to analyze defects in the image.
- AI upscaling for low-res images.
Cons
- Can't fix white balance or color cast issues.
- Slow saving speed for some images in certain versions.

3. Adobe Photoshop
- 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 enhancement software 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
- Fix blemishes, remove red eyes, and retouch (for skilled hands).
- Generative Fill for photo refinement (Firefly required).
Cons
- Heavy use of AI features can limit users on cheaper plans.
- It demands significant system resources, causing performance issues on general PCs.
4. Magnific AI
- Platform: Online.
- Pricing: Premium - $174/year or billed monthly at $20, Premium Plus - $405/year or billed monthly at $45.
- Max Resolution: 10K creative upscaling with sublime model, 2X upscaling with photo models.
- Best for: Cloud-based, generative upscaling, photo editing, and image generation with MCP workflows. Also works for video content.
Magnific AI is widely known as one of the best creative image upscalers online, with generative models to hallucinate details for your images and upscale up to 10K. It also adds models to enhance real world photos, with a maximum of 2X upscaling.
If you prioritizes detail recreation over fidelity, such as generating textures while upscaling banners, posters, and Midjourney images, use the Magnific sublime model. When faithful restoration is required, such as for this boy photo, use the Portraits preset and switch to the photo model. To avoid halo around edges or a harsh look, dial the sharpness slider around 7%-12%.
Note: Founded by Javi López and Emilio Nicolás as a two-person startup, Magnific AI was initially launched for creative upscaling and style transfer. Javi is active on Twitter sharing comparisons, model updating news, and occasional credit giveaways, gaining a large user base from the AIGC community. Freepik acquired the startup in 2024, and in April 2026, the company rebranded the entire platform under the name Magnific.
Pros
- Add details and textures for concept art and illustrations.
- 10K creative upscaling that holds up at large format printing.
Cons
- Not specifically built for RAW, DNG, and camera files.
- In the Freepik (Magnific) subscription, you may end up paying for a broad suite of tools that you don't fully use if your main need is photo enhancement.
5. Upscayl
- Platform: Windows, macOS, Linux, and cloud-based.
- Pricing: Free, open-source desktop app; or starting from $24.99 for 300 credits online.
- Max Resolution: 256MP or 512MP depending on your plans.
- Best for: Upscaling anime or photos without additional quality fix.
For non-commercial, low-resolution images, Upscayl is a decent choice as the best free image enhancement software. Its built-in models are free to use for personal images, with 2X and 4X scaling. For users familiar with Github or openDB model downloads, you can also import custom models for Upscayl.
During my tests, the boy portrait photo is run through both the native Upscayl model and the custom ones. As shown in the comparison below, the 2X enhanced image is noticeably sharper using the built-in High Fidelity model, though his skin and hair somehow look smoothed. The custom RealESRGAN_v3 model helps fix the blocky artifacts in the source photo.
Pros
- Free open source image enhancer for quick upscaling; no sign-up required.
- Handy for unifying the resolution of multiple images in batches.
Cons
- No dedicated models or manual adjustments for face restoration.
- Some models are not eligible for commercial use.
6. Let's Enhance
- Platform: Online.
- Pricing: $108-408/year, input 50MB image.
- Max Resolution: 16K/32K.
- Best for: Anyone who wishes to enhance and upscale AI art, photos, web images, digital creations and upscale for printing.
Let's Enhance is a popular online AI image enhancer, especially favored by beginners thanks to its simple, user-friendly interface. It's perfect for those who need to quickly enhance and upscale a few images without any hassle.
The tool comes with built-in models tailored for different types of images and scenarios, such as photos, digital art, smart enhancement, and smart resizing. It maintains the original aspect ratio and can also handle custom sizes, offering flexibility for various needs.
Testing: For realistic photo quality enhancement, we picked the Prime model. You can check the comparison above versus Topaz standard model. The Prime model prioritizes reconstruction, at least for this specific image.
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.
7. 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, when compared with Topaz, 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.
8. 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.
9. Waifu2X 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.
10. Canva
- Platform: Online.
- Pricing: Free without premium AI features; $180/year for one person.
- Best for: Quick image enhancement directly within your designs, social media graphics and presentations.
Unlike the standalone photo enhancement software on this list, Canva works best when you're already accustomed to its template-based design workflow. For instance, when creating marketing materials or social media posts, you can easily enhance image quality, upscale images, and restore clarity to graphics directly within your project.
As shown in my tests below, the upscaling feature helps restore definition to facial features, the jacket, and the striped collar while avoiding an aggressively sharpened look. After upscaling, the Auto Adjust feature in Canva's Edit tool further applies color and tonal corrections.
Pros
- Automatic photo enhancement in your broad design workflows.
- Sync your edits across web and mobile app.
Cons
- Not built for low-light, grainy, or degraded old photos.
- No dedicated noise reduction models for camera RAW files.
11. chaiNNer Open-Source
- 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.
12. VanceAI
- Platform: Windows, Mac, or Web version with cloud AI processing.
- Pricing: $0.05/credit, $108/year online, or billed monthly without 50% discount. $99/year for the desktop app.
- Best for: Pay-as-you-go causal tasks to restore and colorize images.
VanceAI is a popular image enhancer with AI tools. It is designed for automatic image restoration, colorizing, and photo cleanup. For old photos with creases, scratched and spots, the AI algorithms will help fix those area. Optionally, you can colorize black and white photos, set a larger resolution, and sharpen the image.
It outputs decent quality, though the credit-based pricing can make trial and error costly. For example, higher upscaling levels consume additional credits, while using tools such as sharpening, denoising, or photo restoration also requires separate credits.
Pros
- Fix compressed image and generate textures for plants.
- Bonus background remover, colorizer, and photo-to-cartoon features.
Cons
- No free trials to preview the before and after effects.
- Credit costs can add up quickly using multiple enhancement tools.
Comparisons of the Best AI Image Enhancers
For detail restoration, we examine how the image enhancer handles faithful detail preservation and recovery. For creative upscaling that generates new textures or details, it can be either beneficial or undesirable depending on the image type, user needs, and intended use.
How We Picked the Best AI Image Enhancers
We identified some of the most frequently mentioned photo enhancers and image tools, tested them against a batch of images: a grainy low-light photo with high ISO noise and color speckles, an old family photo with a blurry face, a web-compressed photo, a Midjourney AI image needing 4K upscaling, and camera RAW files if the tool accepts formats such as .CR3, .ARW, .NEF, .ORF, etc.
During testing, we evaluated each tool across the following aspects:
- Output Image Quality: Perceptual quality, maximum upscaling resolution, how it handles detail restoration, and whether the image looks natural without over-sharpening or a waxy, cartoonish look.
- Auto enhancement vs. manual controls: Will the tool automatically process the image, or it also offers model selection, sliders, parameters, or other controls for fine-tuning the result.
- Efficiency: Batch processing capabilities, processing speed, and performance on average computers.
- Sustainability and support: Is it from a trusted developer, receives regular updates and incorporates new technologies, and offers technical support or an active user community? Does it clearly specify the terms for commercial and personal usage?
Based on these criteria, we selected the best AI image enhancement software and online tools that outshine others in all or most of the above aspects.
Tips: How to Choose the Most Suitable Tool for Yourself
If you prefer to avoid the subscription-mode while reaching a natural and clearer output quality, Aiarty Image Enhancer offers a free license to fully explore the feature.
For free and open source options, Upscayl and Waifu2X works nicely on anime upscaling and photos with custom models. For online processing without installation, use Let's Enhance or Canva if you are inside an editing workflow.
