Optimizing and reducing PDF file size
Click on the Advanced Optimization, which will launch the PDF Optimizer dialog.
To use the default compression settings, choose Standard from the Settings up above.
Adjusting any of the settings in the PDF Optimizer automatically switches the Settings from Standard to Custom.
To give you an example, while in the Images option, Color Images over 225 ppi will be downsampled to 150 ppi.
And the Quality here I have set to Medium.
So, let's say I change the downsampled version of the Color Images to 100 ppi, you can see that the PDF Optimizer setting changes from Standard to Custom.
You also have the option to save that as a preset.
So, I could call this Angelo Optimized and click OK to save it.
And you can see that it's now an option in the Settings dropdown menu.
If I didn't want to use that anymore, I could simply select it and delete it from my Settings.
There are other compression settings on the left-side menu that will further reduce the size of the PDF.
From the Make compatible with dropdown, you can choose Retain existing or one of the other versions of Adobe Acrobat, you can see them listed here.
Once you have all the settings in the PDF Optimizer to your liking, go ahead and click OK and you can now save your optimized version of the PDF.
I do recommend renaming it compressed, this way you're not confusing the original with the compressed version.
Once you've done that, go ahead and click Save.
Let's have a look at the original document size compared to the optimized version we just compressed in Adobe Acrobat.
You can see the original was 4.6 MB, and the compressed optimized version is now 715 KB.
You now have a real understanding of how to export and compress PDF documents with Adobe Acrobat.
Give these techniques a try with your own projects and see just how easy it is to manage your PDF documents.
Again, my name is Angelo Montilla, and I'll see you in the next video.
