In such cases, an AI image upscaler is the most effective solution to enlarge low image resolution while preserving natural detail. In this guide, we'll explore the best AI image upscalers available today and help you choose the right tool for your needs.

Best AI Image Upscalers for Enlarging Images in 2026

Before diving into detailed reviews, here is a quick comparison of the best AI image upscalers in 2026. This table highlights key factors such as pricing, maximum upscaling capability, AI models, and supported features to help you quickly find the right tool for your needs.

How to Test the Best AI Image Upscaler

To evaluate the performance of an AI image upscaler, you should test it using different types of images such as portraits, low-resolution photos, and highly compressed images.

Key factors to evaluate include:

• Detail preservation: Check whether fine textures remain sharp after upscaling.
• Noise reduction: Evaluate how well the tool removes grain and compression artifacts.
• Upscaling limit: Test how the image looks at 2x, 4x, and higher magnifications.
• Natural appearance: Ensure the result does not look overly sharpened or artificial.

A good AI image upscaler should balance sharpness and realism while avoiding over-processing.

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

Price: Free trial, $75/Premium

Aiarty Image Enhancer is a desktop AI image upscaler focused on natural detail reconstruction rather than aggressive sharpening. Unlike some AI image upscalers that prioritize hyper-sharp edges or stylized textures, Aiarty aims to preserve balancing sharpness and natural detail restoration rather than over-sharpening or artificial-looking results.

In addition to resolution enhancement, it also integrates denoise, deblur, face enhancement, and artifact removal into the same workflow. This AI image upscaling software also supports multiple professional workflows, including RAW image processing, batch upscaling for large image collections, and enhancement of both real photos and AI-generated images.

In testing:

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 upscalers, but the tradeoff is fewer halos and more realistic texture retention.

Workflow, UX & Speed:

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, then preview the result and export.

Besides AI 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.

Bottom line: 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.

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.

Try Magnific AI Image Upscaler

In tesing:

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, this improvement comes with a clear trade-off. The generative nature of the model 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.

This makes Magnific less suitable for scenarios where fidelity is important, but extremely powerful for creative exploration and visual enhancement.

Workflow, UX & Speed:

When upscaling images in Magifnic, users can adjust multiple parameters such as creativity, resemblance, HDR intensity, and texture enhancement, along with optional prompt-based guidance for further control. So achieving consistent results often requires experimentation across different settings.

Today, Magnific is no longer just an AI image upscaler. The platform is increasingly positioned as a full AI creative production ecosystem that combines image generation, enhancement, video tools, collaborative workflows, and large-scale creative assets into a unified platform. Compared with traditional photo-focused upscalers like Topaz Labs, Magnific is much more aggressive and stylized in how it reconstructs detail.

Bottom line: Magnific AI is best suited for users who want creative, stylized, and generative upscaling rather than faithful image restoration. It excels at producing cinematic, high-impact visuals, but may significantly modify original image details depending on the selected mode and settings.
