Free Image Resizer Options with Devices

Now, let’s take a look at some ways you can resize images using tools included in the devices you may use.

Windows

Windows has a couple of tools that can be used to resize images, such as Photos and Paint. The Photos app makes it relatively easy to resize an image by following these steps.

Open the image in Photos.
Click the More Options icon (three dots in the top right).
Choose “Resize.”
Select one of the preset options. You can also choose “Define custom dimensions,” which will open a separate window to enter custom image dimensions.
If you want the image to maintain its proportions during resizing, be sure to check the “Maintain aspect ratio” box. This will scale the photo to maintain proportions with any dimension change.
Click “Save a resized copy” to save the new version.

Paint can also be used to resize images easily within Windows by following the below steps:

Make a copy of the image. This is just in case anything gets messed up, the original will be preserved.
Right-click the image, choose “Open with,” and then choose Paint from the next menu.
Choose the “Resize” option from the top menu.
You have two options for resizing: Percentage and Pixels. Percentage will resize the image to whatever entered percentage of the original photo. Pixels will resize it to the number of pixels entered. This can be handy for platforms that require certain pixel dimensions.
Input your desired values in the text boxes next to “Horizontal” and “Vertical.”
Click the box next to “Maintain aspect ratio,” or leave it unchecked if you want to change proportions.
Select “OK” to apply changes.
Save the new version of the image.

Right-click on the chosen image.
Choose “Open with Preview.”
