Improved Method to Batch Resize Images in Adobe Photoshop CS4

Insights17 Comments

I recently wrote an article on how to batch resize images in Adobe Photoshop CS4. If you have been reading any of my recent articles on the site you will know by know that I had a laptop hard drive crash and I lost some settings. One of the settings was the Photoshop Action I had created to batch resize images. Anyhow while configuring the Action I decided to play around more with Photoshop to see if there was another way to resize images and sure enough I found a better way if you don’t mind saving the images as JPEG’s instead of GIF’s.

Adobe Photoshop CS4: Batch Resize Images With Photoshop

Insights21 Comments

I used to use a third party application to batch resize images as a certain size is required to display properly on my personal blog. Anyhow I use Adobe Photoshop to manipulate images in many other ways and wanted to see if it would do the same batch resizing which would require one less application to be installed. Sure enough Photoshop does a great job of batch resizing images to any set sizes you prefer.

**NOTE** After writing this article I discovered a different way to resize images that is actually much easier. I wrote a new article located here describing the method which utilizes the Photoshop Image Processor.

In the example scenario below I resize images based on height and width maximum size settings. The width cannot be larger than 640 pixels and the height cannot be greater than 480 pixels. Follow the instructions below to set up a batch resize action followed by automating the batch resize of numerous images at the same time.

How to Batch Resize Image from Linux Shell with ImageMagick

Insights2 Comments

ImageMagick is a really cool product. Not only is it open source but its very powerful tool. My goal was to figure out how to batch resize images while keeping one side 640 pixels wide. I ended up using ImageMagick’s mogrify by issuing the command below at my CentOS shell prompt.

mogrify -resize x640 *.jpg

or

mogrify -resize 640 *.jpg

Depending on which side you want to be 640 pixels. If you would like for image magic to make the largest side 640 and constrain the proportions use the following command.
