Scaling Page Content in Adobe Acrobat Pro DC
Before Adobe Acrobat Pro DC, it was not possible to scale pages from e.g. 5×7″ to Letter size, or form A4 to A5 by changing both the page size, and scaling the page content to fit the new page size. All previous versions of Acrobat had to offer was the crop tool, and it’s “Change Page Size” option to either crop out a portion of the page, or to make the page size larger, but in both cases, the size of the page content was not changed.
In Acrobat Pro DC, Adobe introduced a new scaling feature in the Preflight tool. Because Preflight is a Pro-only feature, this is not available in Acrobat Standard.
Acrobat comes with a number of sample profiles that demonstrate the tool, but none of them is very useful (unless all you want to do is scale to A4 sized paged, or always use a certain scaling factor). I will show how a new fixup can be created that actually prompts for the dimensions of the new target page size. In my example, I will scale to a target size of 6×9″, but that can be any size, and you can use other units besides inches as well.
This is a Preflight option, so we need to open up the Preflight tool first (e.g. search for “Preflight” in the “Tools” area):
Once the Preflight dialog is up, select the “Single Fixups” category (the wrench icon in the screenshot):
Now use the “Options” menu and select to create a new fixup:
This will bring up a potentially confusing looking interface – at least if you’ve never been in here before – but when you follow my instructions, it should be pretty straight forward:
Use a descriptive name for this new fixup, then select the “Pages” category and search for fixups that have “scale” in their name and select the one named “Scale pages”. Now we need to fill in some data in the lower part of the dialog. You see the two orange buttons next to the short and long edge fields? Click them – one after the other – and fill in some values:
For short edge use these values:
Label: Short Edge (in)
Default Value: 6
Internal Name: short_edge
And, for long edge use this:
Label: Long Edge (in)
Default Value: 9
Internal Name: long_edge
If you are using a unit system different from inches, your default may be different.
Now back on the main dialog, we need to adjust a few more things:
Set the units to “inch” – or to whatever your preferred units are. The “Fit from inside (add white space)” option specifies that the original page should be scaled so that it fits within the new target rectangle, and that the remaining space, not covered by the original page should be filled with white.
Now you can select the fixup and apply it to your open document. It will prompt you to select a target page size in inches (you can just accept the defaults in your case), and it will scale all pages in your document.
In a recent update to Acrobat DC, Adobe changed the way variables get added to the user interface. When you just click assigning a variable to either the short or the long edge, Acrobat will not remove the number that is already on the line, and will just insert the new variable at the beginning of the line:
You need to remove the number at the end of the line, so that only the variable (from “<" to ">“) remains on the line:
