You need to merge two PDFs, compress a large file, or split one long document into smaller parts, but you do not want to upload private files to a random website. This stirling-pdf download for pc guide shows you how to get the free open-source PDF toolkit, how to set it up on Windows 10 and Windows 11, and how to merge your first PDFs. Stirling-PDF runs on your own computer, so your files stay with you.
