よくある質問
›Are my PDFs uploaded?
No — merging happens entirely in your browser via pdf-lib. Your files never leave your device.
›Is there a file count or size limit?
Limited only by your browser's memory. Most laptops handle dozens of multi-megabyte PDFs without issue.
›Does it preserve bookmarks and metadata?
Yes — bookmarks, links and document metadata from the source PDFs are preserved in the merged file.
›Can I reorder the PDFs?
Yes — drag to reorder before merging. The merged PDF follows your chosen order.
›Is the merger free?
Yes — fully free, no signup, no file count limits.
