Whether you’re a Web developer, Web designer or blogger, you’ve probably had to deal with the headache of converting many images to different sizes and formats. It’s not much fun if you have to convert all of them by hand. Batch image processing can reduce this process from hours of work to just a few simple clicks.

With batch image processing, you can specify a size or file type, and then a script runs to convert the images. You can process hundreds or thousands of images with just a few clicks. And nearly every image processor comes with a unique feature set.

Many of the articles here on Smashing Magazine have screenshots that have to be resized and configured to fit within the website’s layout. We use batch image processors to quickly resize all of the screenshots and larger images that we feature in the articles.

Types of Batch Processors

Batch image processors usually come with some very standard functions:

  • Resizing images,
  • Scaling images,
  • Converting to different image formats.

Some image processors also perform some advanced functionality, such as graphic editing (rotating, blurring, borders, adding watermarks), and some can even create slideshows, display other types of multimedia and perform other advanced functions.

Image processors are worth their weight in gold if you’re a designer or developer spending a good chunk of time converting images by hand in Photoshop. Let’s take a look at 15 useful batch image processors for both Mac and PC.
