Use the script to send an image from Photoshop to compress-or-die.
Copy it to the Photoshop Scripts folder. Overwrite what’s there if you’re asked.
Windows: C:\Program Files\Adobe\Photoshop CS...\Presets\Scripts
Mac OS X: Applications/Photoshop CS.../Presets/Scripts
Allowed file formats: JPEG, PNG, GIF, WebP, SVG (max. 8 MiB)
If you work professionally with images and photos, they should be displayed with the best possible quality and be as small as possible.
However, all other compressors hide the numerous adjustment possibilities (or its developers do not know the possibilities of the JPEG algorithm) that are necessary to get the best out of the images. Either they just compress each image with the same settings or they state that they use clever algorithms to create the optimal image.
These are just a few examples of how many possible compression scenarios and use cases there are. Getting the most out of an image is therefore only possible with a preview of the result with maximum freedom in the settings.
If you always wanted to know how the JPEG compression works under the hood I want to recommend this article to you. It was important to me to write an article that is reasonable for every level of understanding.
Furthermore it contains 7 valuable tricks to reduce the file size of your JPEGs by exploiting the technical functionality of the JPEG compression algorithm.
