The PDF merging process combines multiple Portable Document Format files by concatenating their page streams and creating a unified document structure. Our algorithm preserves original formatting, fonts, images, and hyperlinks while maintaining file integrity. Formula: Output PDF = PDF₁ + PDF₂ + PDF₃ + ... + PDFₙ (where pages are sequentially combined)
Suppose you have three separate PDF documents: Invoice_January.pdf (2 pages), Invoice_February.pdf (3 pages), and Invoice_March.pdf (2 pages). Using 2MergePDF, you upload all three files, arrange them in chronological order, and merge them. The result is a single Quarterly_Invoices.pdf file containing 7 pages with all invoices combined in perfect order.
