Image Optimizer

Permalink 1 user found helpful
We've just released Image Optimizer, a (paid) add-on that reduces the file size of JPG, PNG, GIF, and SVG images.

- Smaller images, expect at least an average of 10% size reduction;
- Faster loading websites;
- Higher rating by search engines and e.g. Google PageSpeed;
- Progressive JPG images, which results in a better loading experience;

Do you want to try the add-on first? Please send a PM, and we will send you credentials to a test concrete5 installation.

Feedback and suggestions are welcome of course!

HI A3020,

This looks like a super useful add-on.

I use pngquant on a regular basis for compressing PNG files. The reduction in file size is substantial and without any visible reduction in image quality.

I was able to test the Image Optimizer add-on and see what kind of file savings were possible. It looks like all images will be optimized, at least a modest amount, but poorly optimized JPEG and PNG files are greatly reduced in size.

- A large PNG file with a transparent background was 484KB. After optimizing it was 156KB.
- A medium size JPEG file was 44KB. After optimizing it was 23KB.

The savings will depend on the image and if it is already optimized or semi-optimized.

I can see this add-on being used in combination with the core Image Uploading automatic resize feature. This would address the common problem of users uploading very large, unoptimized images and damaging page load performance.

Image Optimization (v2.0) now also integrates with TinyPNG ( You can obtain an API key to optimize up to 500 images per month for free. This addition is especially useful if you don't have server access to install image optimizers locally.
