How to Resize Pictures in Bulk

happy-kitten

People who take or download a lot of pictures have to store gigabytes of image data. Even though, most of the time, there is no practical reason to store a picture with, say, a 5760 × 3840 pixels resolution, when the display you are using is much smaller.

Thankfully, the amount of data stored can be easily reduced by using a simple and free software tool.

This tool is called Image Resizer and is created by Brice Lambson.

Note

In Windows XP, there used to be a set of cool tools called PowerToys which also included an image resizer. Since that project has been abandoned, Windows 7 and later users can benefit the same way from using Brice Lambson’s Image Resizer.

Download and Install

Simply download the ImageResizerSetup.exe file and install it by double-clicking on it.

Image Resizer will be added to the context menu of all image file extensions.

So, when you right-click on an image file’s name or icon, there will be a new item listed in its context menu called Resize pictures.

Obviously, you can also select many image files and resize them in bulk.

Usage

After clicking on the Resize pictures menu item, Image Resizer’s window will pop up. Be patient as it may take a few seconds to load even on a very fast machine.

You can select several options.

First, select a size for the output images from Small, Medium, Large, Mobile, or define a Custom size.

If you select the Custom mode, you can further define whether you wish to Scale or Stretch the original image. And whether you wish to define its size in Pixels, Centimeters, Inches, or Percents.

Next, select whether you want to scale down the images or Only shrink pictures. This means that only those images will be resized, which are larger than the size you defined in the previous step.

Then, you can decide whether you wish to Replace the originals or create new files with the resized images. The newly resized images will be placed in the same folder holding the original image files and will be clearly differentiated in name.

Should you wish to place the resized pictures into a different folder, right-click and drag the original pictures above that folder.

When you let the mouse go, a small context menu will pop up.

Select Resize pictures here from that menu.

And, finally, you can decide to Ignore picture rotations or not.

The last step is to click on the Resize button.

The time it takes to resize the images depends mainly on the number of images that are being processed.

Once the resizing process is done, Image Resizer will automatically exit.
