Processing photos for the web — rotating, resizing, renaming and compressing -– can be tedious and time consuming, especially if you do everything one file at a time.

Batch Resizing Using Command Line and ImageMagick

Using the Actions palette in Photoshop, you can record all of those little tweaks you perform to prepare your photos, then “replay” them to instantly complete the same list of tasks on multiple images. This process, called a batch operation, can save you a ton of time since you’ll be able to zip through each of the same, tedious tasks any number of times with a single click of the mouse.

For this How To, we’ll use the example of resizing an image from a digital camera. Most digital cameras capture photos in high resolution that are thousands of pixels wide — great for studying the details in a scene but hardly ideal for sharing on the web. We’ll shrink these images to a manageable size that’s easy to e-mail or upload to an online gallery.

ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. It is distributed under the Apache 2.0 license, approved by the OSI and recommended for use by the OSSCC.

The ImageMagick development process ensures a stable API and ABI. Before each ImageMagick release, we perform a comprehensive security assessment that includes memory error and thread data race detection to prevent security vulnerabilities.
