How to Resize Your Images without Losing Quality

If you are new to photo editing and image optimization, it might be confusing whether you can change the file size of your picture without losing its quality or reducing its physical dimensions. The short answer is yes, you can optimize images without quality loss, but the longer answer lies within compression algorithms and other technicalities. This article will help you understand why images need to be resized, how come they might lose quality in the optimization process, and which programs you can use to reduce the size of your images without changing their overall quality.

Common Reasons to Resize Images

Many websites and blog platforms have limitations on the size of image uploads. For example, if your website or blog operates on WordPress, there is a limitation on the size of the images you can upload. You can’t upload images heavier than 1MB, but good quality images with medium or high resolution weigh more than that. That’s why you need to change the size of your images without loss of quality. Images also get resized for website optimization purposes. Many internet users tend to drop a page that takes too much time to load, especially when they surf the web with a smartphone. Each web element on a page takes some time to load, and heavy pictures in high resolution take a lot of time to fully load and be correctly displayed. Since you can change the size of images without the loss of quality, the best use of this is to improve the loading speed of your website. Sometimes you will need to resize your images for social media platforms so that they are lighter. Heavier photos are also hard to send via email, especially if you use an email signature with images at the end of the email so you will have to optimize them as well. Images that come straight from your camera, even if you take pictures with your smartphone, are unnecessarily high in their resolution and should be resized before they are uploaded to the web.

Why Images Might Lose Quality When You Resize Them

Images on the web are usually in Bitmap format. Bitmap includes common file types such as JPG and PNG. Each image consists of thousands of pixels which you can see when you zoom into a picture, and each of these pixels has its own place in the file. The more pixels an image has, the higher its resolution, and the larger its size is. When you try to make the file size of your images smaller, you can accidentally mess up the resolution, resulting in a picture with blurred or pixelated parts. For example, when you change your image size with, let’s say, a standard Windows program MS Paint, it automatically reduces the quality of an image to make it lighter, which sometimes can be visible when you enlarge those images. Nevertheless, in our digital age, you can easily resize images without quality loss, or resample them. Resampling is a term that is used to describe the ability of a program to analyze your image and change the number of pixels instead of just changing their size or scaling. Tools that allow you to make pictures lighter without any visible quality loss usually have complicated algorithms that analyze each image you want to optimize and cut out some of their colors which you can’t see with your bare eye.
