Optimizing Images with ShortPixel

With ShortPixel installed on your website, you can easily optimize existing and new images. The plugin allows you to bulk-process all existing photos with just a few clicks. You can also set it up to automatically optimize new pictures as you upload them. ShortPixel offers various settings to customize the optimization process to your specific needs.

What do these Compressions mean?

Lossy is the best option for most users. The images processed with Lossy algorithms are the most optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you continue to use Lossy optimization.

Glossy is the best choice if you still care about Google Insights but believe that a slight loss of page speed is an acceptable compromise for top-notch image quality.

Lossless optimized images are pixel-by-pixel identical to the originals, but they offer a minor size reduction compared to either Lossy or Glossy processed files. If you want your pictures to remain untouched, then select this option.

Thumbnail compression

For optimal performance, enable this setting, as thumbnails are usually the most viewed images by the website’s visitors and can drive the most traffic


ShortPixel, by default, will back up the original unoptimized images. You can restore single photos or bulk restore all if needed.

Remove EXIF

EXIF stands for “Exchangeable Image File Format.” It is a type of data stored inside digital photos. For example, the time of a picture, the camera and the settings used to take the image. Enabling remove EXIF is recommended, as it will reduce the file size.

Advanced Settings

  • Optimize media on upload – ShortPixel Image Optimizer will automatically optimize the newly added images.
  • Optimize Retina Images: This option will enable optimizing any @2x retina-specific images.
  • Optimize Other Thumbs – Certain plugins can create additional thumbnail files not included in your media library. By enabling this option, ShortPixel will compress these thumbnails as well.
  • CMYK To RGB Conversion – By converting your images from CMYK to RGB, you are optimizing your images for viewing on your device’s screen and compressing your image file sizes further.

Measuring the Results

After optimizing your images with ShortPixel, you can measure the results with GTmetrix and Google PageSpeed by testing your website’s load time and comparing the file size of optimized and unoptimized images.

The scores serve as an indicator of how a website is performing overall. These scores are necessary for the average user to comprehend the outcomes. Please remember that a website’s performance can be more accurately determined using your computer or device browser.

Page speed is typically measured in seconds or milliseconds, not by a numerical score. Although a high score may appear desirable, the aim is to identify any issues causing your site to load slowly and to take the necessary steps to address them.

What about pricing?

ShortPixel’s monthly pricing is super competitive because it offers a wide range of options that can fit the needs of any budget. It provides plans for individual users and businesses, ranging from free to enterprise-level, that are scalable so that users can upgrade or downgrade their plans as necessary. You can also buy a credit package or sign up for their unlimited service.


ShortPixel is a must-have WordPress plugin, offering powerful features that make image optimization a breeze. Overall, Shortpixel is an invaluable asset for any WordPress website, helping to improve website performance and reduce page loading times.
