Batch Scale PDF quickly scales many PDF files to any size PDF. Originally intended to scale sheet music of different sizes, Batch Scale PDF should work on most PDFs, for any purpose. It’s the quickest way to resize many PDFs with one click! Batch Scale PDF scales the original PDF to the specified size of the output PDF by the largest percentage possible while still fitting within the dimensions of the output PDF. The aspect ratio of the original PDF doesn’t change, so if the output page size is different than the original PDF, Batch Scale PDF will automatically add margins to the output PDF as needed. For both Mac and Windows.
