The term resizing image is nothing new. We’ve heard it for years! But when it comes to images, sometimes the word resizing can be a little bit confusing. Because it can convey two shades of meanings, one is to change the image dimensions, which can usually be achieved by increasing/decreasing the amount of horizontal and vertical pixels, say, increasing the pixel resolution of an image so that it still looks as crisp on a larger display as it is displayed on a smaller screen; While the other may be interpreted as the change of the image file size, which can usually be realized by cropping or compressing the image, say, compressing an 12MB image to 2MB so as to upload it to certain social media platforms where there is always a maximum limit regarding file size.

The main objective of this article, however, focuses on the former, that is, how to resize (increase or decrease) image without losing quality. We’ll talk about the top 5 most widely used software tools each with great details. Thus, if you are also on the hunt for such a tool yourself, hope this article can be of help to you.
