PDF-BatchStitch is the fast utility that combines multiple PDFs into one file, along with the option to set the number of copies for any of the PDFs.
PDF-BatchStitch quickly combines many PDF files into one PDF.
Simply drag and drop your files onto the application window, or click the Add Files button to locate them in your file browser.
If you plan on printing double-sided, but want to ensure each file starts on the “top” side of the paper, be sure to click the Add blank sheet to the end of files with an odd number of pages checkbox.
Click Combine to save the file. A window will appear prompting you for the file name and location.
