Resize Images without Losing its Quality

Have you ever tried resizing an image to make it larger without losing its Image Quality? This usually results in loss of Image quality where the enlarged image looks blurry and unprofessional. This is a common problem and is a common type of question. Unfortunately, small images or highly compressed images (especially with JPG format images) offer very little to work while trying to expand them. It is not possible to display information that is not there.

Recently one of my friends asked me if it was possible to resize a small image and make it larger without losing its Image quality. In this article, we will show you how to resize images to make them larger without losing its quality.


If you are using an image rich website or blog, it is important to find ways to resize and maximize images without losing Image quality. Caring for a proper and high-quality performance of your website imagery is not only with the whole customer experience but also with advanced SEO results. Google does not hide the fact that it really loves images on websites, especially if they are well optimized, formatted and pleased with the eyes.

What is Image Quality?

When we talking about photography, the word ‘Image Quality’ is also called ‘IQ’, it is an image feature that measures the estimated image degradation. You have probably tried to enlarge images and then it became somewhat blurry or amateurish. The thing is that all the JPEG and PNG images we are using on the websites are Bitmap image files. Those images have pixel dimensions which are almost invisible from a normal viewing distance, but if you try to zoom an image, those pixels become visible in the form of squares. And whenever you are resizing those Bitmap images to make them larger, the pixels are not only extended, but new blank ones are added to the image for enlarging. As a result, you are having a new version of your original image, that is larger but of lower Image quality.

Why Images Lose its Quality When Enlarged?

Most graphics software provide a range of different options for resizing images, some options work better on some images or image types. Works best, in general, may not be the best for your specific images. this image editing software reduces or enhances these pixels for resizing images. That’s the main reason when you change an image in a small size then there is no Image quality loss. Mainly because those pixels also appear less. On the other hand, when you change the size of an image to make it larger, these expanded pixel images are showing more than being blurred and pixelated.

A bitmap is the most used image format on the web. BMP file format is also called a bitmap image file or device independent bitmap file format, or simply bitmap is a raster graphics image file format that is used to store bitmap digital images independently. The bitmap image is made up of thousands of pixels. If you zoom in, you can actually see those pixels as squares. All your JPEG and PNG files are bitmap image files.
