Best WordPress Image Optimization Plugins

ShortPixel Adaptive Images (SPAI) is a plugin launched by a Romanian company that resolves all the performance issues by not only reducing the image size but also by serving the images from a CDN.

Key Features:

Choose a compression level among Lossy, Glossy or Lossless algorithms depending on your site’s requirements. The Lossy algorithms give you the smallest possible images prioritizing the speed of your site.

Glossy compression assures top notch image quality with slight compromise in the page speed.

Lossless images are pixel-by-pixel identical to original images with only a slight reduction in size.

• WebP support: The WebP image format reduces the size of the image considerably without affecting the quality much. With ShortPixel, we can select .webp format for all images served from the CDN
• EXIF removal: ShotPixel lets you remove the extra information such as Author, location, camera model etc., thus reducing the weight of the image further.
• Smart Crop: ShortPixel smartly the crops the images
• LQ Image Placeholders: These are very low-quality images which appear on the page during its initial load. Once the page is fully loaded, the original quality images will replace them.

Pricing: 

There is a free version that allows optimizing 100 images per month. However, there are paid versions as well starting from $3.99/month upto $1000/month for more number of images and dedicated servers.
