FAQ
Questions, answered.
Are my files uploaded anywhere?
No. The merge happens entirely in your browser using pdf-lib. We don't see your files and never could.
Is there a file size limit?
Only your browser's memory. Most modern devices handle 100+ MB combined easily.
Can I reorder individual pages, not just files?
Yes — see the PDF Reorder tool on the Hub for fine-grained page-level control.
