Why Split PDF Files?
Splitting PDFs lets you extract only the specific pages you need from a large document. This is invaluable when you want to share individual chapters from a book, extract specific invoices from a compiled statement, send just a few relevant pages from a lengthy report, or separate a scanned multi-document batch into individual files.
Splitting also helps dramatically reduce file size for email attachments that need to stay under inbox limits, makes large documents much easier to organize into logical sections, and enables you to distribute only the relevant portions of a document to different recipients or departments.
