Why Merge PDF Files?

PDF merging is essential for combining multiple documents into a single file. Common scenario: You have a signed contract (3 pages), supporting documents (8 pages), and attachments (5 pages)—instead of sending 16 separate files, merge them into one professional document.

Use cases: Combining invoice pages with receipts, merging chapters of a report, creating presentation handouts from multiple sources, consolidating scanned documents, assembling legal documents with exhibits, and preparing application packages with multiple forms.

Real example: HR departments merge offer letters, NDAs, and benefit summaries into one onboarding packet. Instead of emailing 6 separate PDFs to new hires, they send one comprehensive 18-page document—easier to manage, harder to lose pages.

Privacy & Security

All PDF merging happens locally in your browser using JavaScript. Your files are never uploaded to servers, stored in databases, or transmitted over the internet. The merged PDF is generated on your device and downloaded directly—complete privacy guaranteed.
