Learning how to resize an image in Photoshop is important, as resizing images is one of the core skills you need to get under your belt when you first start using the application.

By resizing an image, you can control the size and resolution of the image, and therefore the file size, allowing you to turn huge 75MB RAW image files into manageable 10MB JPEGs that are suitable for web use.

Knowing how to resize an image will also allow you to tailor the precise size of the image to the overall canvas you're working on.

Resizing an image in Photoshop is thankfully very easy — as you'd expect from one of the best photo editing software applications. But like with most things in Photoshop, it isn't exactly obvious how to do it when you first get started.

Never fear though, this guide is here to show you the way to do it. So, without further ado, here's how to resize an image in Photoshop.

How to resize an image in Photoshop

  1. Press Option + Cmd + I (macOS) or Alt + Ctrl + I (Windows)
  2. Or Click Image > Image Size
  3. Enter your new size and resolution
  4. Click OK

Read on to see full illustrated instructions for each step.

With an image open in Photoshop, press Option + Cmd + I (macOS) or Alt + Ctrl + I (Windows).

2. Enter new sizes and resolutions

Now enter your desired sizes and resolution. If you have the width/height lock button enabled (linking the width and height) you can change one and the other will automatically scale.

You can also change the resolution, which will change the file size and quality of the image.

Resample is on by default — this shrinks the image down by removing pixels and increases the size by adding pixels. It's perfect for most uses. Untick it if you'd like to shrink the image down without losing any pixels — for example if you'd like to keep the resolution you have.

3. Click OK

When done, simply click OK.
