How to Low-Res a photo (21.html)

The easiest way to reduce the resolution of a digital photo (using Windows) is to use the IrfanView program. After you have downloaded IrfanView, it is a very simple procedure:

To download Irfanview:
  1. Go to
  2. Click on "Download"
  3. etc
To Low-Res a photo:
  1. On your Desktop, Double Click on the Red Bear icon for IrfanView
    (not on the IrfanView Thumbs icon).
  2. Click on "File" then "Open"
  3. In "Look In", select the folder containing your photo.
  4. In "Files of Type", select "JPG/JPEG"
  5. Select the photo you wish to change
  6. Click on "Open"
  7. Type "S" on your keyboard
  8. At the bottom, select "Show options dialog"
  9. In "save options" dialog, select "Set File size"
  10. ... and set the file size to be "999" KB
  11. In the "Save Picture As" window, suffix "_M" to the photo name.
  12. ... and Click on "Save"
  13. It will then create your Low-Res photo
  14. To see your Low-Res photo, click on "File" then "Open"

The second time you reduce a photo, many of the options will be saved, and you won't need to redo them.
A small (2 megapixel) file will take a few seconds to reduce.
... A 25 megapixel file will take 75 seconds to reduce.
These small 1 megapixel photos only take a few seconds to upload to the web.
