MediaSizer is a plug-in for use with Adobe Acrobat which allows you to change the media page sizes in Acrobat.
For example, most documents produced in the US are created on letter-sized paper and most in Europe are on A4. This product quickly changes PDFs from one media format to the other, without having to repaginate and recreate the PDFs in the original application.
Several standard media sizes are included and additional sizes can be added.
