For many years now, when I needed to batch convert images – for example to convert file formats or resize images – I've been using Microsoft Office Picture Manager. That tool still works great but, of course, it is only available by purchasing Microsoft Office and it hasn't apparently been updated in quite some time.

So, on the hunt for something free and modern, I discovered XnConvert.

Let's go over the basics:

• Free
• Cross-platform (Windows, Mac, Linux)
• Simple UI that is optimized for the task
• No ads or adware
• Supports many file formats

My experience with it has been excellent. I now have a replacement for Microsoft Office Picture Manager. I highly recommend you try it out the next time you need to convert images.
