Best for: increasing resolution and all-round image editing
OS: Windows 10 64-bit or later and macOS Big Sur (version 11.0) or later
In this guide, we’ll show you how to increase the resolution of an image using two methods in Adobe® Photoshop®. The first tried and tested method is to increase the image size itself.
- At the top of the Adobe® Photoshop® window head to: Image > Image Size or use the keyboard shortcut Alt + Ctrl + I. A new window will appear where you can alter the resolution of the image.
- It’s important to note that there are myriad unit measurements from which to choose. Next to Dimensions in the window there are options to navigate between: Picas, Centimeters, Millimeters, Points, Percent, Pixels, and Inches which aid in producing all kinds of mixed media for both print and online. We are changing the resolution of the image, so we’ll highlight the dropdown box Pixels.
- Look further down and you’ll find there are options for Width, Height, and Resolution. Type into either Width or Height boxes to determine how many pixels you’d like your image to be resized to.
- Bear in mind that the chain lock button to the left of the boxes will constrain the aspect ratio if engaged, making whatever number you type into the box also affect the other to keep the same aspect ratio as the original image. If this is a problem, you can fix it by altering the Resolution box. A lower number (such as 72) is more useful for web use where file size should be kept to a minimum.
You may be wondering how to change the resolution of an image using Artificial Intelligence? A newer way to increase the resolution of a photo is to add a neural filter.
- By heading to Adobe® Photoshop®’s newer Neural Filters (Filter > Neural Filters) and selecting the Super Zoom filter you can make a selection on the image.
- Now use the variable sliders to adjust the image before clicking OK for a high resolution, cropped version of the original photo. This is particularly useful for images that need to maintain detail while also adjusting composition.
