Have you ever tried resizing an image to make it larger but instead lost the image quality?
When you try to enlarge an image, it can look blurry and unprofessional. A picture is made up of thousands of pixels, and when you increase its size, those pixels become visible. As a result, you see a dull and low-quality picture.
In this article, we will show you how to resize images to make them larger without losing quality.
Why do Images Lose Quality When Enlarged?
A bitmap is the most commonly used image format on the web. All your JPEG and PNG files are Bitmap image files. A bitmap image is made up of thousands of pixels. If you zoom in, you can actually see those pixels as squares.
Each of these pixels is mapped to a fixed location on the image, hence the name Bitmap.
Most image editing software shrinks or enlarges these pixels to resize an image. This is why when you resize an image to a smaller size, there is no visible quality loss. Mainly because those pixels become even less visible.
On the other hand, when you resize an image in WordPress to make it large, these enlarged pixels become more visible, making the image look blurry and pixelated.
The solution is to compensate for each enlarged pixel to match the properties of its nearest pixel. This method is called Fractal Interpolation or simply Fractals. It produces a much better result when an image is enlarged using this technique.
Let’s take a look at how to use the most common image editing software for your WordPress website to resize pictures. You can use the links below to hop to any method with just a click.
Method 1: Enlarging Images Using GIMP (Free)
GIMP is a free alternative to premium tools like Adobe Photoshop and Affinity Photo. It can also be used to enlarge images with minimum quality loss. However, we should warn you that the result will not be as good as Perfect Resize, which we’ll show you in method 3 below.
First, you need to download and install the free software on your computer. It’s available for both Mac and Windows devices.
After that, open the image you want to resize in Gimp and go to Image » Scale Image.
Next, enter the width and height to set your desired dimensions.
Now, choose Cubic as the Interpolation method under the ‘Quality’ section, and click on the ‘Scale’ button when you’re done.
That’s all, you can now export the enlarged image in different formats, like PNGm JPEG, HTML, and more.
Method 2: Enlarging Images Using Irfanview (Free)
Irfanview is a compact photo editing program that’s also free to use. It is only available for Windows-based operating systems and provides a smarter way to resize images and make them larger.
Simply open your image in Irfanview and go to Image » Resize/Resample.
This will bring up the image resize popup window. First, you need to enter your desired image size in the ‘Set new size’ field by defining the width and height.
After that, you need to select resample under the ‘Size method’ section. Choose the ‘Lanczos (slowest)’ option from the filter dropdown menu.
Lastly, check the box next to ‘Apply Sharpen After Resample’ and click the OK button when you’re done.
Irfanview will now resize the image, which you can then save to your computer.
You might notice that free tools don’t do a very good job of resizing an image to make it larger. However, by adjusting sharpness and image contrast, you can enlarge images and minimize the quality loss in the process.
That said, you can also use a premium tool to make sure that the image remains sharp and clear when it’s enlarged.
