Best FREE AI Tool to Upscale, Unblur, Sharpen Images

If you're looking for a completely free AI tool to upscale images or enhance blurry, pixelated photos, this one is hard to beat. You can use it on your computer without any internet connection. Let’s dive in!

Introduction to the Tool

The tool I'm going to share with you today is called Upscale. It offers both a cloud version and a desktop version. Although the cloud version promises features like face enhancement and quicker processing, it isn't available yet, so you'll need to join a waitlist. Today, we will focus on the desktop version, which you can run on your computer without any internet connection.

Installation Process

Compatibility: I installed this on a laptop without a dedicated Nvidia Cuda GPU. Here are the display adapters to prove the point.
Download and Install: If you're using Windows, click the appropriate download link, and install the .exe file. Note that the download size is around 540 MB. Once installation is complete, launch the program.

Using the Tool

Upload an Image: You can either upload a single image or batch upscale multiple images.
Select the Model: Choose from several upscale algorithms, like Ultra sharp, balanced, or faster models.
Adjust Settings: Typically, it upscales to 4X by default, but you can adjust this. You can also stop the upscaling at its original size to simply enhance the details.

Test Images

I tested three images: a small icon, a photo of a dog, and a portrait of a person. For each, I showed both the original and the upscaled versions to highlight the improvements.

Small Icon:
- Original: Blurry and pixelated.
- Upscaled: Significantly improved details.
Dog Photo:
- Original: Clear but lacks detail when zoomed in.
- Upscaled: Enhanced fur details and sharper grass.
Portrait of a Person:
- Original: Small and pixelated.
- Upscaled: Much clearer. Different algorithms added varied levels of realistic detail.

Additional Functions

Batch Upscale: This feature allows you to upscale all images in a folder at once. The tool saves the upscaled versions in a separate subfolder.

Overall, the quality is impressive, especially considering it is free to use. I recommend checking it out.

Conclusion

The Upscale tool is a powerful, free-to-use AI for image enhancement that even rivals some paid tools. You can use it indefinitely and without an internet connection. Be sure to explore its various settings and models to find the best results for your images.
