Optimus Plugin Review

In our previous guide, How to use WebP images in WordPress, I have mentioned that you can use Optimus plugin to enable WebP images in WordPress. I don’t use Optimus only to be able to use WebP images in my WordPress installations but also to provide me with lossless image compression.

What does Lossless and Lossy Image Compression mean?

Lossy Image Compression:

It is the compression method where some data from the original file is lost. This results in a significantly reduced file size, but it also means there is quality loss. WordPress uses Lossy compression rate of 82% (as WordPress 4.5) to compress preview images.

Lossless Image Compression:

It is the method where the original file data is perfectly reconstructed from the compressed data which means that the size is reduced and the quality is almost the same.

Do you really need to compress your images?

Simply, YES! According to the shown stats from HTTP Archive, the most of a website’s page weight is made of images. So images should be the first thing you need to optimize in your website.

Interesting Stats

Optimus reduces the file size of uploaded media files. Depending on the image and format, reductions in the size of up to 70% are possible.

For better result, I recommend choosing these options and leave the other unchecked:

  1. WebP files.
  2. HTTPS connection.

Optimus Bulk Optimizer:

To optimize your images in bulk, head to Media -> Library and follow the above screenshot. When the images are compressed, you can see the compression ratio for each image under “Optimus” column in your Media Library.

Before I start using Optimus, I have tried multiple services and I found Optimus has the best results, it’s cheaper than Kraken and Imagify (one price for unlimited images) and built with the makers of KeyCDN, the CDN I use and trust (check my KeyCDN Review).

Check Optimus Now!
