Modern digital cameras have a high resolution and therefore create photos with a large file size, which can quickly fill up your hard drive. If you have a large photo collection, you might want to decrease the size of the JPEG pictures on your hard drive to regain drive space. You might also want to resize a JPEG picture to upload it to a Web server or to send it as an e-mail attachment. You can do so in Paint, the graphics editor native to Windows.

Skill level:
Moderately Easy


  1. 1

    Click "Start" on your taskbar, and type "Paint" in the search box. Press "Enter" to launch the program.

  2. 2

    Click on the "Paint" menu, and select "Open." Use the file browser to find the photo you want to downsize.

  3. 3

    Click on "Resize" under the "Image" category in the "Home" tab.

  4. 4

    Activate the check box next to "Maintain aspect ratio." This will prevent Paint from distorting your photo while resizing it. Then type a new value in the "Height" or "Width" field. You must type that value as a percentage of the original size of your picture. For example, typing "30" will resize your picture so that it occupies 30% of the size of the original photo.

  5. 5

    Click "OK" to finish resizing your JPEG photo. Then press "Ctrl" and "S" simultaneously to save your photo.
