Optimize Images on Windows Locally

Optimize Images on Windows Locally

by Adrian RandallNovember 22, 2016

We all know sites are becoming more and more image heavy which places more emphasis on the need to optimize images. There are a lot of free tools out there that can be used online to optimize images but the fact is, if your site has 1GB of images it is going to take you a long time to:

  • Download from your website
  • Upload to be optimized
  • Download once they are optimized
  • Re-Upload back to your site

So is there a quicker way? Well yes but you’ll still need to download and re-upload them at least once.

The easiest way is to use Caesium.

Caesium allows you to open an application on your Windows desktop, select a folder and then optimize the whole folder at once locally in seconds.

To use Caesium, either download it from the Caesium site:


Or if the link does not work then download the portable (no install) copy directly from the link below:

Once you’ve download Caesium just unzip it then open Caesium.exe.

  • Click on Settings
  • Then ensure “Scan subdirectories when you open a folder” is ticked
  • Then from the toolbar select File->Open Folder
  • Then Set the output folder. Do this by creating a new folder in the same directory as the folder you’d like to optimize and append ‘-optimized’
  • Click Compress and wait for it to finish:
    optimize images
  • After that re-upload the images and you should now pass all tests on the web looking for optimized images
