What is the difference between a PDF merger and a PDF splitter?

A PDF merger combines multiple separate PDF files into one single document. For example, you might merge three quarterly reports into one annual report. A PDF splitter does the opposite — it takes one large PDF and breaks it into separate files by extracting specific pages or dividing the document. Use a merger when you need to consolidate information from multiple sources. Use a splitter when you need to share only specific sections of a large document, like extracting a single chapter from an ebook or separating pages for distribution. Both tools are essential for efficient document management, and MiniToolsPro offers both.
