The biggest problem Google finds when site speed is an issue is the fact that images are not optimized - both for desktop, but especially for mobile. (read more about what Google says about mobile image optimization in 's post http://tgcafe.it/1B0qikR)
I was doing some search on this very issue yesterday as I was starting to upload loads ;) of images to my new traffic generation course at TrafficologyBlueprint.com. (sorry you can't buy it yet, but you can sign up to receive a notification on when it becomes available or even become one of few beta testers: TrafficologyBlueprint.com)
I even asked and - the two people I first think of when it comes down to blog images - for suggestions.
Dustin suggested JPEGmini
Thomas suggested Compressor.io
Both seem to be great tools, but what I didn't like about them was the fact that you have to upload your images to the server, then download the optimized versions back to your computer.
When I have dozens of images per each section of the course, it becomes quite a chore.
Then I found ImageOptim (https://imageoptim.com/) and it cut out that unnecessary and time-consuming upload/download step - I love it!
How it works:
1. Download the software to your Mac (sorry, it works for Macs only!).
2. Simply drag'n'drop images or folders into the ImageOptim window.
They'll be optimized in-place - right where they are on your computer.
You can see a 2.2MB image go down to 1.9MB in a matter of seconds. You can re-optimize the image to reduce it even further.
Loss of quality? None as far as my eye could tell.
It's a keeper!
Any suggestions for a similar free tool for PCs?
