Reduging the Size of a Picture File

This section provides a tutorial example on how to reduce the picture size and file size using 'Paint' program.

Suppose you have a picture downloaded from a digital camera called pic_001.jpg. The file size is about 2,100 KB. This is good for printing a hard copy. But it is too big to put it on your personal Web page. You could use Paint to reduce the picture size and file size.

1. Run Paint.

2. Select menu "File > Open". The open dialog box shows up.

3. Locate the picture file, pic_001.jpg and click the Open button. Your picture will be loaded into Paint.

4. Select menu "Image > Attributes". The Attributes dialog box shows up.

5. The dialog box tells you that the picture is 2592 pixels wide and 1944 pixels high. Click the Cancel button to close the dialog box.

6. Select menu "Image > Stretch/Skew". The "Stretch and Skew" dialog box shows up.

7. Enter 25% in Horizontal Stretch and Vertical Stretch fields and click the OK button. The picture will be reduced to 25% of its original size as shown in the picture below:

8. Click the OK button on the dialog box to reduce the picture size to 25% in both directions. The resulting size will be about 648x486 pixels.

9. Select menu "File > Save" to save the picture with the reduced size.

10. Look at the picture file, pic_001.jpg, again. The file size is reduced to 77KB.
