Merge PDF FAQ
Before you start.
Are my PDFs uploaded to a server?
No. The browser reads and combines the selected files locally.
Can I merge more than two PDFs?
Yes. Select multiple PDF files and PDFbuff combines them in the displayed order.
Does merging reduce quality?
PDF pages are copied into the output. PDFbuff does not intentionally rasterize or recompress them during merge.
Do I need an account?
No account is required for the free merge tool.
