Merge vs Combine — What Is the Difference?
These terms are often used interchangeably, but technically: merging appends all pages of multiple PDF files into a single new file, preserving all existing content. Combining may also refer to creating a PDF portfolio (a ZIP-like container) — a different format. iCreatePDF performs true merging, producing a flat, universally compatible PDF.
