How to Batch Downsize Images on Windows Desktop

Every once in a while, we encounter simple problems with our daily tasks. However we don’t want to spend a lot of time and money just to figure out its solution because we only do those specific tasks sometimes.

One day while I’m working, I have to downsize thousands of images because downsizing them all speeds up file rendering. As a website developer, we don’t want our site to load static assets longer than a second but then heavy files make it even worse.

The question is, how can we downsize all of our images in one batch without having to do it one by one in a photo editor or any application software?

Personally, this is the most convenient and hassle free solution I discovered:

Step 1

Go to your folder and select all the images you want to downsize. Right click then and you can see the options dialog, choose Send to then Mail recipient.

Step 1

Step 2

When you choose Mail recipient it will open another dialog. Choose Picture size then select the Smaller option and click Attach. On some windows, a pop-up dialog will show saying No Microsoft outlook profile has been created…. Just ignore this message but don’t click OK because it will remove all of your output images.

Step 2

Step 3

After clicking Attach, on the search box of your desktop search for a folder named %temp% with percent sign (%) included. Open this folder and you can find all the downsized images. You can then copy those images and paste them on your desired location.
