Enlarge Images Easily Without Quality Loss

Have you ever tried to use an image online that looked pixelated or otherwise low-quality when enlarged? Most of the buzz in using online images is how to make the file sizes of the images smaller, but that often results in a quality loss that can leave you disappointed. The good news is that there are several AI-backed tools available to assist you in enlarging your images without losing quality.

There are a number of tools that can accomplish this, such as:

They all work similarly, though their free plans have different limitations. For the purposes of this demo, we are going to use https://bigjpg.com.

Upscaling an Image

The main page contains a standard upload window that allows you to choose an image on your device to upscale.

When your image has finished uploading, select “start.”

The configuration window will appear. First, select the type of image you are using. Then, pick a factor by which to increase the image. For this tool, the free version is capped at 4x.

In testing, I tried a few different images. I found that photos best showed the power of the noise reduction aspect of the tool. For this, I used one of our stock photos of a young man at the library. Here is the original:

First, I enlarged the image 4x, and didn’t apply any noise reduction. Click/tap on the image below to make it full size. Depending on the size of your screen, you may be able to see how fuzzy the image looks in his face and his shoulders. That’s the “noise.”

Same image, but larger and lower quality.

I started from the original image and enlarged it 4x again, this time also opting for the highest noise reduction. Click/tap on the image below to make it full size, and note that this image has all of the “noise” smoothed out to make the picture quality appear better.

You may wonder why they offer different levels of noise reduction. To see the answer, compare the last image with the original. Where the AI has reduced the noise, it has also “guessed” at how to edit the image and left it looking a bit like a soft filter has been applied. In some cases, you may want to balance that effect with the noise for a better outcome.

Summary

Now that AI technology has become available to the consumer market, free image editing tools have gotten much more sophisticated. There are several sites that will allow you to upscale and enhance your images without a pricey software product. Have you used any of the tools we listed? Do you have another image upscaling tool you love? Let us know about it in the comments.
