Frequently Asked Questions
How many PDFs can I merge?
You can merge as many PDF files as you need. The merge happens entirely in your browser using the pdf-lib library.
Can I reorder the files before merging?
Yes. Once uploaded, use the up and down arrows on each file card to rearrange the merge order before combining.
Are my PDFs uploaded to a server?
No. Merging is performed locally in your browser. Your PDF files never leave your device.
Is the merged PDF quality affected?
No. pdf-lib copies pages without re-encoding, so the merged PDF preserves the quality of all source documents.
