Using IrfanView For Thumbnail Creation


This is a quick tutorial in using the excellent imaging tool, IrfanView, to batch process your images.

To give this article some practical context, let’s suppose you have 100 JPEG images that you need to be rescaled.

Rather than go through and open up each image with Photoshop, I looked around on the net and found an excellent batch processing application. irfanView is a freeware application created by Irfan Skiljan that runs on Windows 9x, ME, NT, 2000, XP, 2003 , 2008, Vista, Windows 7 and Windows 10.

Here’s what I did (note: make sure you make backups of originals before proceeding!) to rescale all the images:

  1. Bring up the batch conversion window via File | Batch Conversion
  2. Choose Work as Batch conversion – Rename result files
  3. Choose output format as JPG
  4. Clicked the Use advanced options
  5. Clicked on the Advanced button to bring up image settings
  6. Ticked the resize box and set the new width as 50% and height as 50%
  7. Changed the name pattern to “thumb-$N” so my thumbnails would be named thumb-originalfilename.jpg
  8. I then navigated in the directory tree to the folder of my original images
  9. I added all images and then removed those that didn’t need to be resized
  10. I then clicked on the Use current (look in) directory button to lock in the output directory for the result files to be the same directory as the originals
  11. Then, pressed the Start Batch button

After I was done, all my images were resized by 50% and had the name thumb-{imagename}.jpg. This saved me boatloads of time. I couldn’t imagine having to go to Photoshop and opening up 100 images and resizing them by hand. This definitely saved me at least 2 hours of work.

If you have a lot of images that need to be resized, cropped, flipped, rotated and even watermarked, irfanView is a fine, fast, and easy imaging tool to get the job done.
