How to Reduce Photo Size to 300Kb

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.

You can compress your digital photos to reduce their file size.

Microsoft Paint

Step

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

Step

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

Step

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

Step

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

Step

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

Step

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

Step

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

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

Microsoft Office Picture Manager

Step

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

Step

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

Step

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

Step

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

Step

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

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