How To Enlarge Thumbnails Without Being Blurry

What is a thumbnail image?

A thumbnail is a compressed preview image of an original one. The most important benefit is the reduced size with considerably quicker loading time on your website. The size of a thumbnail image can vary, depending on the site and platform. However, smaller sizes make it easier for businesses to provide more content without too many delays. Now you may wonder how to enlarge thumbnails without being blurry?

Why do we need to enlarge thumbnails?

Whether your thumbnail image is taken on your own or found on online galleries, you might want to enlarge it sometimes. For instance, the surrounding areas can be too frustrating and make the main subject less attractive. Thus, you need to “zoom in” a bit. The same thing holds true for portrait pictures in which you want to focus on the beautiful face of the model instead of the whole body.

I have found some solutions to enlarge the thumbnails for other purchases. However, no luck. For example, I have read the article on CNET that introduces a plugin called Hover Zoom. The plugin is invalid and the developer is not going to maintain this program. It shows 404 after redirected to its download page.

So I realized that enlarging thumbnails is not a simple job. A common challenge of enlarging thumbnails is that the image can become blurry. This is because digital pictures are comprised of pixels. When you want to make them bigger, there is not sufficient information to display all of the colors and details. As a result, your thumbnails would reduce in overall quality. Fortunately, there are many solutions to convert low resolution to high resolution. And AI Image Enlarger is one of them. In this article, I will compare the AI solution with some traditional methods.

Traditional methods to enlarge thumbnails

You can easily enlarge thumbnails on your computer by using the resize function. It is available in most photo editing tools. Photoshop is one of the most popular options.

However, there are two drawbacks to using traditional methods. Firstly, most of them can be costly. You have to pay for the licenses to use the software. Also, it might take time to learn how to use the tool and special technique.

I use an original small thumbnail and add the image to Photoshop. Enlarge the thumbnail by using its resizing tool. And here is the result.
