How to Reduce Photo Size to 300Kb

By Bennett Gavrish

Images that you transfer from your digital camera to your PC are usually several megabytes in size. Large file sizes are good for maintaining a picture's resolution, but it can be very difficult to share photos that are large in size. If you want to reduce the size of your photos to 300 kilobytes, you can use Microsoft Paint or Microsoft Office Picture Manager. Images of 300 kilobytes are easy to email or post on the web.

Things You'll Need

  • PC running Windows XP or later

Microsoft Paint

Step 1

Open the "Start" menu and expand the "All Programs" list.

Step 2

Go into the "Accessories" folder and click on "Paint."

Step 3

Open the main Paint menu in the far upper-left corner of the window and choose the "Open" option.

Step 4

Navigate to the location of the picture you want to edit and then double-click on it.

Step 5

Go to the "Home" tab in the toolbar and click on the "Resize" button in the "Image" section.

Step 6

Select the "Pixels" radio button and make sure the "Maintain aspect ratio" box is checked.

Step 7

Replace the horizontal and vertical values with lower numbers. If you make both of the dimensions less than 100 pixels, you can guarantee that your image will be less than 300 kilobytes.

Step 8

Hit "OK" to resize the picture and reduce the file size.

Microsoft Office Picture Manager

Step 1

Open the "Start" menu and expand the "All Programs" list.

Step 2

Navigate to the "Microsoft Office" folder and then click on the icon labeled "Microsoft Office Picture Manager."

Step 3

Highlight the thumbnail of the photo that you want to reduce to 300 kilobytes.

Step 4

Go to "Picture" in the top menubar and select the "Compress Pictures" option.

Step 5

Choose one of the radio buttons on the right side of the screen. When you select a radio button, the compressed size of the photo will appear underneath. In most cases, the "Email messages" radio button will reduce a photo's size to 300 kilobytes or less.

Step 6

Press the "OK" button to compress the photo and reduce its file size.
