maxresdefault 44

When creating artwork with AI tools like Midjourney and Stable Diffusion, the generated images often have lower resolutions. To sell your work on image platforms or offer your designs on Pod websites, you need high-resolution images. To achieve higher resolutions, you usually require a more powerful graphics card or need to upscale lower-resolution images. For most users, I recommend utilizing free AI image upscaling tools for intelligent image enhancement and enlargement. Today, I’ll introduce five straightforward and user-friendly image enhancement tools.

1,Tool One – Code Former Replicate:

Replicate is an intriguing website where you can explore pre-deployed open-source models. These include various open-source language models, such as Stable Diffusion, open-source text-to-image models, and a variety of image upscaling enhancement models. Taking the Codeformer model as an example, it excels in repairing portraits and has received acclaim on GitHub with 7.9K stars. Sample images provided by the official source showcase Codeformer’s strong portrait restoration capabilities and its ability to intelligently enhance and perfect facial features.

You can use this tool by logging in with your GitHub account. If you don’t have an account, you can easily register for a free GitHub account through the provided link.


Now, let’s upload an image and select default parameters, like a 4x upscale. The system will then enlarge a blurry image, and you’ll notice significant improvements in facial clarity following AI processing.


Maintaining the same settings, you can upload a digital portrait generated by Stable Diffusion, and the results are quite impressive.


Additionally, Codeformer supports high-resolution image enhancement. Upload a clear anime character image, and the system will optimize image details, resulting in finely detailed facial features.


In addition to using this model in Replicate, you can also run it on Google Colab and Hugging Face Space. Visit Codeformer’s GitHub page via the provided link to access the tool. However, please note that Hugging Face Space may have slower performance. Therefore, I recommend using Replicate or Google Colab to run this model.
