Change Multiple Image Sizes All at Once

When uploading images to the web, the size of the image can sometimes cause issues. Cameras output images in very large pixel sizes. Websites will usually not want to run images at 3000 X 4000 pixels, at least not run them very smoothly.

Changing the size of the images is a necessary part of adding images to any website, besides Facebook and other technologically advanced sites that have powerful image re-sizers built in. Have a lot of images that need to be uploaded and all need sizes changed? This is where a cool free piece of software can assist. Download Now ButtonBulk Image Resize Manager is an open source tool that can be downloaded from and will allow multiple images to be re-sized all at once.

To change multiple image sizes all at once, download the program Bulk Image Resize Manager and launch the program (make sure to uncheck the bloatware that tries to download during the install process). Once the program is open, create a new folder and put all the images to be re-sized in that folder. Put the name of this folder in the box “Source Folder Path” and then change the percentage of image size reduction/increase that you want, i.e. 25%, 50%, 75%, 150% etc.

Then click “Change Image Size” and watch the program work through the size change rather quickly. Your new folder containing the re-sized images will now pop up and show the contents.

Now take the newly size changed images and upload them to your website. That’s all there is to change multiple image sizes all at once!

Jophiel grew up on a ranch in Paradise Valley, Montana near Chico Hot Springs. Working on the ranch instilled work ethic and self motivation. Filled with this drive, Jophiel started mowing the local school's yards twice a month throughout the summers, at the age of 12. He moved to Billings in 2004, where he has been deeply involved in the local business community ever since. A serial entrepreneur, Jophiel has ran multiple businesses in our local community. The first business, a janitorial and carpet cleaning company, founded in 2005, has employed over 50 locals. Moving on to the media industry, Jophiel and several partners founded Green Directory Montana in the spring of 2007. Green Directory's sustainability ranking software awarded points based on sustainable or "green" actions. These points counted towards a business's total "Green Score," which in turn ranked them against other businesses in their category and throughout the entire site. It also featured a limited edition print version distributed annually. A business acquisition allowed Jophiel to focus on new projects, and a few close business colleagues and Jophiel started Rocky Mountain Mr. & Ms. Magazine, a lifestyle publication for men and women in the Magic City. After a year and a half at the helm of RM3 Magazine, the business was purchased. He now runs a web development company SkyPoint Studios and fathers his son Jaoquin, who plays football, basketball, soccer, and is learning snowboarding from his dad. Recently, has expanded to locations in Havasu, Arizona & Vegas. SkyPoint Studios is a market leader in both Billings & Havasu and Jophiel is working on building that same level of market dominance in Vegas.
