How to batch resize pictures on a PC
- Right-click on your desktop (or in your Documents or Photos folders) and choose ”New Folder” and name it
- Go to your photos and choose all of the ones you wish to resize. Click the first photo, then hold down your ”CTRL” key and continue single-clicking on each photo you wish to resize. Once you have chosen them all within a specific folder, let go of the CTRL button and right-click on any of the photos and choose ”Copy”.
- Now, go back to your desktop and double-click to open the folder you created. Once it is open, right-click anywhere and choose ”Paste” so that the photos you just copied automatically show up there!
- If you have photos in other folders you wish to resize in this batch, follow the steps above until everything you need is in your new folder. Now…
- With your new folder open, click on ONE of the photos. Then, hold down the ”CTRL” button and press the ”A” key. This will select all of the photos quickly for you. Now, right-click on one photo, choose ”Send To” and then ”Mail Recipient”. Don’t worry – we aren’t actually emailing these!
- A little window to attach files will show up now. Choose the size you wish to change the photos to here. The window will show the quick progress and then a box will likely appear stating there is no program associated to use. That’s okay – we don’t need one! If you do use Outlook or Thunderbird or another email program, ignore it when it opens.
- Go to your search box in Windows and type %temp%. You’ll see an option to open up your Temporary folder. Go ahead and click it and voila! Your resized photos are right there!
