Image Size for Blog Posts

A quick test of one image using various methods of compression to find the optimal image size for blog posts.

I’ve done this test a few times, with different images in the past. There is never one result fits all. Because each individual image has its own characteristics which affect the compression amounts. If you’re really trying to find the best of the best – with just one method. It won’t work. It’s best to find the most efficient method, that fits the majority of images. That way, you reduce your workload.

If you’re looking for the perfect score on a page load test. Then sure, you can try all of these methods to find the optimal one. But personally, I’m not sure I’d bother. Life is too short.

All of these methods are using a 2000px long edge image, all are using the ShortPixel Plugin.

As you can see. There isn’t a lot in it. From the smallest file at 432kb to the largest at 481kb, we’re only talking 49kb difference. But that is a 10% saving. For the others, it’s all pretty close. And there’s no clear winner. My personal current setting is Quality 66 and not using JPGmini. I took this approach after reading on the Fuel Your Photos website about Dylan and Corey’s recommendations. From the images I’ve tested so far, I agree with them, that adding JPGmini into the mix, simply isn’t worth it. On a couple of images I tested, it was actually a larger file size when I used JPGmini. So that really decided it for me.
