Frequently Asked Questions
Is merging PDFs free?
Yes. TetraKits Merge PDF is completely free with no signup or usage limits.
Are my files uploaded to a server?
No. Merging happens entirely in your browser. Files never leave your device.
How many PDFs can I combine?
Add as many files as your browser memory allows. Typical sessions handle dozens of documents.
Can I merge specific pages only?
This tool merges entire files in order. To extract pages first, use split PDF.
Will merged PDFs keep bookmarks?
Basic merge combines page content. Complex bookmarks and forms may not fully preserve — test critical documents after merging.
One PDF from Many Files
Contract appendices, scanned receipts, and report chapters often arrive as separate PDFs that need combining. Browser merge with drag-to-reorder handles the job privately — no email attachments to third-party services.
Because everything runs locally in your browser, it is fast, private, and works on phones, tablets, and desktop computers.
