If you are a blogger and most of your content consists of photos you have shot, there is a good chance that you create needless traffic going out from your hosting server. The reason for this is image metadata.
How Much Image Metadata?
So, how much image metadata are we talking about here? I have tested the images published on several photo-heavy blogs (predominantly food blogs) and there is no single answer.
Some sites are doing a great job in eliminating all metadata from their images. Food blogs, such as Jamie Oliver, Simply Recipes, Pinch of Yum, or Joy the Baker are among such sites. I could hardly shave 0.1% off their image sizes.
The Pioneer Woman is doing a slightly less perfectionist job in this regard. I was able to decrease her image file sizes by 4% to 7%.
How to Remove the Excessive Metadata?
I recommend using ExifTool to remove all metadata from JPG photo images.
It is very easy to use and works fast and in a thorough manner.

How Much Money Could Be Saved?
By using the above mentioned technique a lot of money can be saved. Let’s say that a blogger uses a CDN (
That would mean that she pays about $0.04 (four cents) for each GB (gigabyte) of her outgoing traffic. So, overall she pays $0.04 * 1000 * 30 = $1200 a month or $14,400 a year. In the most extreme case, she could save around 20% of these expenses, so about $2,880 each year.
That’s the price of a new camera right there!
Not to mention that less traffic means less electricity consumption which in turn means a smaller impact on the environment. If you care about such things…
