• ON1 Resize AI shows great strengths in facial optimization, but it has weaknesses with very low-resolution images.
• Tools like imglarger and letsenhance provide surprisingly good results, even with free versions, and can be a real alternative to paid applications.
• Remember that optimal image quality often depends on the original resolution of the image.

Step-by-Step Guide

1. Installing ON1 Resize AI

Open ON1 Resize AI in the latest version (2023.5). When you first open it, the user interface looks simple and straightforward. Here, click on "Open Photo" or upload a sample photo to see how well the program works.

2. Resizing Images

Select an image with low resolution (e.g., 720 x 480) and go to the "Image Size" menu. Enter a desired new size, for example, 4000 pixels.

3. Before-After Comparison

Turn on the before-after comparison function to see the changes immediately. You can also zoom in to 100% to accurately assess the sharpness of the image.

4. Adjusting Facial Optimization

Activate facial optimization and confirm the selection. This significantly improves the details in the face, but be aware that the overall image quality may vary. So be prepared to make some adjustments.

5. Noise Reduction and Sharpening

If you are satisfied with facial optimization, you can activate noise reduction. Adjust the settings to achieve the best result without making the image appear too soft. Then, check the sharpness and consider increasing it if necessary.

6. Comparison with Higher-Resolution Images

Upload an image with higher resolution (e.g., 1280 pixels wide) and enlarge it again to 4000 pixels. You will notice that the program achieves significantly better results here.

7. Using Other Tools

Also, test other tools like imglarger by uploading your images and adjusting the enlargement settings. This website has a user-friendly interface and provides quick results.

Also, take a look at letsenhance and imgupscaler. These tools often provide better results in hair and eye optimization. Experiment with the settings and pay attention to the quality of the results, even with free applications.

9. Comparing Results

Compare the results from different tools. Sometimes, a free tool outperforms a paid one - especially when it comes to the finesse and sharpness of the details.

10. Conclusion and Storage

Summarize all adjustments and click on "Save". Choose the desired format (e.g. JPG) and adjust the compression rate to optimize the file size for your needs.

Summary

In this guide, you have learned how to effectively enlarge images using various AI tools. The correct application of these programs depends heavily on the original image quality. Use the described steps to assess both the strengths and weaknesses of the respective tools correctly.
