How to resize an image in Photoshop on your mobile device

As phone cameras have improved in recent years, the size of photo files has increased with them. Uploading big files to your blog or your limited cloud storage is not always ideal. Thankfully, there are a few easy ways to resize your image using different Adobe Photoshop applications on your phone or Chromebook.

It’s not recommended that you increase image size when editing, as this can often cause it to become pixilated. Instead, snap your photos at a higher resolution and then scale down as necessary to keep good image quality. This quick guide takes you through the process of reducing your image size in the Photoshop Express and Lightroom mobile apps and in Creative Cloud Express online. These are all free to use, but you may need to create an Adobe account.

Adobe Lightroom

Lightroom is a popular option for people who want to edit their photos and videos while on the go. Its various presets make for easy editing to make your images punchier, and also has the tools to create your own. As with Photoshop Express, resizing an image comes as one of the last steps when you are ready to export it.

1. Open the Lightroom app and import an image to your library. You can do this either from your camera or by searching your device storage using the blue buttons in the lower-right corner.
2. Select the imported photo from your library that you want to resize.

Avoid the storage headache

It’s easy to put off cleaning out old and unusable photos until some later date. The last thing you want to get while exploring a new city on your vacation is that “Low on storage space” notification. Especially if you are learning to shoot and edit RAW photos, you can deplete precious storage space quickly. It doesn’t help if you’ve been filling up your cloud storage with large image files either.

So take the time at the end of a day of snapping photos to edit and stay on top of your file management. Your future self will thank you for it.
