Hello and welcome to my blog!
I was recently asked to offer help in resizing a DVD full of 7 megapixel photos. The company didn’t have a Photoshop license, didn’t want to purchase one, so I recommended Irfanview, a little, free and easy to use software, that you can download from Tucows.
Resizing a whole bunch of images, from a DVD, CD, directly from a camera, phone or hard drive, is a piece of cake, if you use Irfanview.
Just start the program (I assume you already know how to intall and start a program on your computer) and press ‘b’. A new window, entitled ‘Batch conversion’, will open.
Select the source, where your original, big images are. If you wish to also include subdirectories, check the ‘Include subdirectories’ button, or press ‘ALT+b’. Click the ‘Add all’ button (middle of the window, has a bunch of buttons near it). If you did everything OK, you should see a list of your images in the left pane.
Now select the output directory (input box in the middle of the window) and under the ‘Work as’ panel, select ‘Batch conversion’.
As the output format select ‘JPG -JPEG Format’ (it should be selected by default). Click on the ‘Options’ button to modify the JPEG compression (90 is the default value, but you can select any other value – between 70-90 highly recommended due to close to none image quality loss).
Check the ‘Use advanced options’ checkbox and click the ‘Set advanced options’ button.
Check the ‘RESIZE’ box (second from the top). Then select ‘Set new size’ and ‘Set long size to’ 800 pixels (or any other value you want, but 800 is recommended if you want to easily upload the image to the Internet). Now check the 3 boxes below: ‘Preserve aspect ratio (proportional)’, ‘Use Resample function (better quality’, ‘Don’t enlarge smaller images’.
Click ‘OK’ in the bottom right corner. Click ‘Start’ (top center) and you’re done.
