How to Resize an Image in Photoshop

Resizing an image is an essential task for everyone. Being a graphic designer, you are responsible for delivering the optimized images to the client. As an individual, you also need to resize the images as per your need.

Optimized images are beneficial for web applications. They enhance the page load speed, prevent your web application from negative SEO, and reduce your website's bounce rate.

While creating a document, usually we keep the standard size of the document. But, later, we need to resize it according to our project.

Photoshop facilitates several tools to change the image size, such as crop, resize, change the image canvas size, etc.

In this section, we will discuss how to resize an image in Photoshop. We will enlarge and reduce the image size.

Change the Canvas Size in Photoshop

We can also alter the image size by changing the canvas size. Basically, increasing the canvas size is useful for adding some extra info around the image. Increasing the canvas size will increase the image canvas from all the sides, and decreasing the image canvas size will crop the image from all the sides. This will also increase and reduce the size of the document.

The Canvas Size option can be found in the Image menu. When we select the canvas size option, it will open a dialog box displaying the current canvas size. We can alter the canvas size in two ways; either by providing the new dimensions or checking the relative box option. This will allow us to specify the size of the canvas in pixels we would like to alter.

Once we are satisfied with the canvas size, click OK to apply the changes.

Let's understand how to alter the image canvas size:

Open the image and navigate to the Image menu and select the canvas size option.

Thus, we can resize the image in Photoshop by altering the canvas size.
