Best AI Image Upscalers: Detailed Tests and Reviews

Aiarty Image Enhancer- Enlarging Low-Res Images Without Losing Quality

Price: Free trial / $59 yearly / $119 lifetime

Aiarty Image Enhancer is a desktop AI image upscaler designed to make low-resolution images larger while keeping them sharp and natural-looking. Instead of simply stretching pixels, its AI models analyze the existing image and reconstruct missing details during upscaling, helping reduce the blur, softness, and pixelation that often appear when a small image is enlarged.

You can upscale low-resolution photos by up to 8× to 4K and higher, easily turn small images into larger versions for printing, social media, e-commerce listings, or other high-resolution uses. It also includes deblur, denoise, and face restoration tools that fix blurry, noisy, or detail loss during image upscaling.

For users who need to enlarge many images, Aiarty supports batch processing and local desktop processing, so images can be enhanced without uploading them to a cloud server.

🔥 Aiarty is offering the image upscaling free with a 7-day free license, full access to its features, no watermarks or limits.

In hands-on testing, Aiarty performs particularly well on portraits and slightly blurry low-resolution images. Facial textures, eyelashes, and hair strands remain natural after upscaling, without the overly crunchy or over-sharpened appearance sometimes seen in tools like certain online AI upscalers.

Noise reduction is another strong area. Compressed JPG artifacts and grain are cleaned effectively while keeping edge transitions relatively smooth. On difficult images, the results may appear slightly softer than more aggressive AI image upscaling software, but the tradeoff is fewer halos and more realistic texture retention.

The workflow is straightforward. Users can drag and drop images, choose an AI model, select upscale ratios like 2×, 4×, or 8× (up to 32K resolution), or a specific resolution for flexible upscaling factor like 1.5x, 2.5x, then preview the result and export.

Besides AI image upscaling, Aiarty also offers a range of built-in enhancement tools, including old photo restoration with facial detail reconstruction, color correction with HDR-style enhancement, and object or background removal for image cleanup before or after upscaling.

Performance depends heavily on GPU acceleration. With modern GPUs, processing is fast even for large images, while CPU-only processing can feel noticeably slower during high-resolution exports.

Best for: Aiarty Image Enhancer is best for users who want realistic, natural-looking AI image upscaling with strong detail preservation and integrated restoration tools, especially when enlarging old photos, slightly blurry images, portraits, etc. that need clean high-resolution output rather than heavily stylized enhancement.

Topaz Gigapixel - Professional AI Upscaler for Sharp Detail

Price: $29/month, or $19/month with an annual plan

Topaz Gigapixel is a powerful software for upscaling images without any noticeable loss in quality. It uses multiple AI models trained for different image types, including Standard, High Fidelity, Art & CG, and Low Resolution, allowing users to adapt the processing based on the content.

Unlike simpler AI image upscaling software, Gigapixel provides a high level of manual control. Users can upscale images from 2× to 6× and fine-tune parameters such as noise reduction, blur removal, and compression artifact correction. This makes it particularly suitable for high-resolution outputs, print workflows, and AI-generated artwork from tools like Midjourney.

In testing, Gigapixel produces extremely sharp results and often recovers micro-details better than most online AI upscalers. However, its aggressive sharpening can sometimes make skin textures look overprocessed or introduce artificial textures at higher enlargement levels.

Gigapixel offers one of the most customizable workflows among AI upscalers. Users can manually switch between models and fine-tune denoise and sharpening sliders, which gives strong control but requires some experimentation to get optimal results.

As desktop image upscaling software, its performance depends heavily on hardware. With a modern GPU, processing can be relatively fast, but large images or 4×–6× upscaling can become resource-intensive and noticeably slower on mid-range systems.

Best for: Topaz Gigapixel is best for users who want maximum sharpness and control over the AI image upscaling process.

Photoshop Generative Upscale– Built-in AI Upscaling for Basic Enhancement

Price: $22.99/mo

Photoshop Generative Upscale (powered by Adobe Firefly) is a built-in AI upscaling feature designed for quick image enlargement within the Adobe ecosystem. It supports up to 4× upscaling and is primarily aimed at improving usability for editing workflows rather than delivering advanced detail reconstruction.

Instead of being dedicated AI image upscalers, Firefly-based upscaling is tightly integrated into Photoshop and Lightroom, with no additional models, sliders, or fine-tuning options. The process is fully automated, making it simple to use but limited in terms of control and customization.

In testing, Photoshop Generative Upscale provides only a modest improvement in image clarity. When starting from a slightly blurry or low-resolution image, the upscaled result becomes a bit sharper and more usable, but the level of detail recovery is limited. Compared to dedicated AI image upscaling software like Topaz Gigapixel, the output appears softer and less detailed.

The main advantage is convenience: users can upscale images directly during their normal Photoshop or Lightroom workflow without switching to another application. However, there are no adjustable settings, model choices, or enhancement controls. Upscaling is generally fast, but limited functionality makes it unsuitable for large-scale or quality-critical upscaling tasks.

Best for: Photoshop Generative Upscale is best suited for quick, in-workflow AI image upscaling when convenience matters more than quality, as the overall performance is weaker compared to dedicated image upscaling software and is not ideal for high-quality print or detail-critical work.

Originally launched as an AI-powered creative upscaler, Magnific has rapidly evolved into one of the most influential AI creative platforms in the industry. Now its generative enhancement technology became deeply integrated into Freepik’s expanding AI ecosystem.

Unlike traditional AI image upscaling software desktop and online that mainly sharpen or enlarge photos, Magnific focuses heavily on generative reconstruction. It supports upscaling from 2× up to 16×, depending on settings, and offers two main modes: Precision mode for more faithful structure preservation, and Creative mode for more aggressive generative enhancement.

In testing, Magnific delivers highly detailed and visually striking results, especially in cinematic or stylized imagery. Surfaces gain richer textures, lighting becomes more dramatic, and the overall image often feels more “produced” or enhanced compared to the original.

However, the generative upscaling can significantly alter original image characteristics. In many cases, facial features, textures, or object structures are partially reinterpreted rather than strictly preserved. Even at lower creativity settings, subtle changes in identity and composition can still appear. So this AI image upscaler is less suitable for scenarios where fidelity is important, but extremely powerful for creative exploration and visual enhancement.

When upscaling images in Magifnic, users can adjust multiple parameters like creativity, resemblance, HDR, texture enhancement, and prompt guidance, but achieving consistent results often requires experimentation. More than a traditional AI image upscaler, it focuses on generative, creative detail reconstruction, producing more aggressive and stylized results than photo-focused upscalers like Topaz.

Best for: Magnific AI is best for creative users who want generative, highly detailed image upscaling. It excels at producing cinematic, high-impact visuals, but may significantly modify original image details.
