Hello

I’m using Adobe PRO and try to optimize a file which contains 99,50% of images.

I try to find the best way to compress the images to have the smallest size without loosing noticeable quality.

When I use the « standard » settings it’s still too large.

Then I let the « transparency » menu at « high quality » and manage to change settings in the « images » menus (I joins a picture of the settings below).

Unfortunately there are a lot of settings I don’t understand. But when I use JPEG 2000 instead of JPEG for compression and put « high » for quality I get a smaller file.

But the quality of the images in the PDF are a little degraded, mainly the texts are  little bit « drooling ».

Please can you share your best configuration in Adobe Pro to get a perfect shrinked PDF containg a lot of images ? Or provide guidance and advises to how improve an optimization ?

Thank you and best regards.

There is always a compromise between image size and image quality. The image quality degradation is more obvious is you select a compression mechanism that is not optiomized for your specific content type (e.g. use a compression method that is designed for compressing photographic images when you are trying to compress a scan of text). What it comes down to is you need to experiment to see what is an acceptable image quality giving you also an acceptable file size.
