In the wake of the recent AI surge, image processing has witnessed remarkable advancements, revolutionizing our digital experiences. Tools like Midjourney offer the creation of stunning AI-generated images, while Photoshop’s AI Generative Fill allows unprecedented photo manipulation. Furthermore, leveraging AI, one can now upscale existing images to 4K or 8K resolutions, performing tasks such as detail restoration, deblurring, pixel correction, and more. Without delay, let’s explore the top AI image upscaling tools available.

1. Image Scaler by Stability AI

Stability AI, a notable alternative to Midjourney, also offers an exceptional AI image upscaling tool. I’ve had personal experience using this tool multiple times, and it stands out for its user-friendly interface and its ability to upscale images remarkably without excessive sharpening.

A standout feature of Stability AI’s image upscaler is its free accessibility for 2x image upscaling. To upscale images further, from 4x to 16x, a subscription to the paid plan is required.

The paid plan includes access to the Stable Diffusion XL model, enabling faster AI image generation, features like relighting, and the capability to remove text from images, among others. Additionally, for those seeking to upscale images while enhancing details, this tool offers that functionality exclusively for paid users.

Although the enhanced features are reserved for paid users, the free tool caters well to most users’ needs, making it worth exploring.

This local processing appeals to privacy-conscious users hesitant to upload personal photos to online platforms.

The app, available for free, seamlessly enhances low-resolution images by up to 16x without any charges. For those seeking custom upscaling models, the paid SuperImage Pro app is an option. Utilizing a neural network embedded in a deep learning framework and the Real-ESRGAN algorithm, the app leverages your device’s GPU to restore image details.

The program offers five distinct modes and harnesses your GPU’s power to refine blurry images. A notable advantage is its capability to batch upscale images, a feature lacking in other free tools.

Remarkably, Remini specializes in enhancing human faces and selfies. It boasts additional features such as creating 90s yearbook-style photos, generating professional resume shots, AI image generation, face enhancement tools, and more.
