Resizing Photos

Photo sizes (height and width) are measured in pixels. In general, more pixels means a bigger file size. When resizing a photo, you will select a new height or width by either typing it in or selecting from a list of values (depending on the application you use). If you can type in the new value, set either the height or width (whichever is larger) to 1024 pixels. If you have a list of sizes to pick from, select one where both the height and width are less than 2000 pixels.

If you are inexperienced at this, we strongly recommend using a desktop or laptop computer to resize your photos (rather than a phone or tablet). The process is much easier with a larger screen and a mouse and keyboard.

See instructions below for the type of device you’re using.

Desktop or Laptop Computer is a free, online tool that allows you to upload images, resize them (and make other edits), and download the new image. This works on both PCs and Macs, and no software installation is required – simply visit the website with your browser.

iPhone or iPad Tablet

The editor in the built-in Photos app does not have image resize functionality. Use a third-party app such as Image Size, available from the Apple App Store.

Android Phone or Tablet

If you have a Samsung phone or tablet, the built-in Gallery app will allow you to resize images. Instructions can be found at How to resize a photo in the Gallery app on your Samsung phone.

For other Android phones and tablets (Google Pixel, Motorola, etc.), use a third-party app such as Photo & Picture Resizer, available from the Google Play store.
