Batch Converting Your Images

While I love Adobe Photoshop and the amount of power it has behind it’s actions, sometimes I like to use a lightweight alternative.

IrfanView is a program I’ve mentioned before, it’s great for flipping through series of images but it’s also great at doing many other things (some of which I’ll mention in future posts), like batch converting. In the following example, I’ll do a quick run through on a real life example, creating image thumbnails.

So, lets start off by opening a folder with pictures you’d like to thumbnail:

Pictures I’d like to thumbnail

Open a picture with IrfanView and select ‘Batch Conversion/Rename’ from the file menu (B is the shortcut key)

Select Batch Conversion/Rename

Click the ‘Add All’ button (or optionally pick and choose the images you’d like to convert). And set your basic options. I made my output folder /thumbs, selected ‘Batch conversion – Rename result files’, made the output format GIF and set my rename mask to $N.t (which means [old image name].t).

Click Add All

Check the ‘Use advanced options’ box and click the ‘Set advanced options’ button.

Advanced options

I set my thumbnail size to 50% height and width but you can choose whatever you please. I also checked ‘preserve aspect ratio’ and ‘use resample function’ but those are optional.

Click ‘OK’ and you’ll be taken back to the previous window, click ‘start’ and bam, you’re done.

You can now navigate to your newly create thumbs folder

New thumbs

And marvel in the glory

Hey, it’s me!

This was a pretty simple example but I’m sure when you went to the advanced options window, the gears in your head starting turning. This program is a great tool, you should really play around with it and try to get the most out of it. I don’t think a day goes by that I don’t use it.
