As a web developer, you’ll inevitably end up needing to resize a bunch of images at some point.
- Installing itch on OSX. Download the latest version from Open Install itch.app; If it doesn't launch the first time - try a second time. We're looking into that particular issue. Note: before v25, itch used to install in /Applications/itch.app. It now installs per-user, in /Applications/itch.app. You might want to remove.

Hercules runs under Linux, Windows, Solaris, FreeBSD, and Mac OS X. Hercules is OSI Certified Open Source Software licensed under the terms of the Q Public Licence.
- While shots featuring the old style scrollbars are prevalent, I added this one in here on account of the control strip in the lower left hand corner, a Mac OS mainstay in the pre OS X days.
- Some files that I download from the internet are being hidden by the os. At first I thought that maybe the difference is that some.pdf files are protected but after review it is not just protected.pdf's being hidden from view it's non-protected.pdf's and some.jpg's too.
Obviously, you can now fire up your favourite image editing software suite like Photoshop, Gimp, etc. to get the job done or turn to dedicated tools for the sole purpose of (batch) image resizing.
While many tools can fulfill the task it can be very tedious to resize a batch of images at once with the same configuration.
sips to the rescue!
Sips is a command line tool that has been around quite some time and comes pre-installed with every Mac and (in my eyes) doesn’t get enough credit for what an awesome and easy-to-use tool it is.
How-To
Let’s assume you have a bunch of images as jpegs that need to be resized so they do not exceed a width of 320px. A sample original image could look like this:
To get this image resized to a maximum width of 320px while maintaining the image ratios (who wants distorted images on his site anyways?) run
to resample all jpg files in the current folder to a width of 320px.
Be aware that without specifying the --out option, the original images will be overridden without any confirmation prompt.

Similarly, you can use sips to resize images to a maximum height of 320px
sips --resampleHeight 320 *.jpg
or to limit both height and width to some value:
sips -Z 320 *.jpg
Non command-line alternatives
Boom rutracker. For the people not feeling comfortable with the command line you also turn to the built-in preview app as described here.
More command-line options
If sips doesn’t provide enough options and capabilities for you, you might wanna take a look at imagemagick, one of the most powerful image editing command line tools, which can also be used in many scripting languages like php, python or javascript.

Btw: sips can do far more for you than just resizing a bunch of images. It’s functionality can also be used in AppleScript under the name “Image Events”.
