Check Image Size

Check Image Size Overview

The Check Image Size module is the module you go to when you need to check the dimensions and file sizes of any image on your site. You can use this module to identify those which might cause performance problems and bottlenecks, then you can edit them accordingly for improved site performance.

Check Image Size Filters

There are 5 filters:

  • All Status - shows all images with every label
  • Warning and Error - shows images with Warning and Error labels
  • Warning - shows images with Warning labels only
  • Error - shows images with Error label only
  • Normal - shows all images with Normal label only

File Size

The file size checks for how many pixels the image contains in bytes. For example, an image of 2,340,000 pixels has a file size of 2,340,000 bytes or about 2.34 MB (this is because there are 1024 bytes in a kilobyte and 1024 kilobytes in an MB).

The recommended file size of images is less than 100 kilobytes for a fairly small image, and within 200 kilobytes for banners and large images.

Pixel Size


  • OK - Image is optimised and doesn’t impact site performance
  • Warning - You should take a look at this image and make the necessary adjustments
  • Error - This image needs to be replaced or readjusted, it has a very negative impact on site performance
