Frequently Asked Questions
How many PDF files can I merge at once?
You can merge as many PDF files as your device memory allows. Merging 5, 10, or even 20 documents is fast and fluid.
Can I rearrange files after uploading them?
Yes! Every file displays as an interactive card. Simply drag cards to set your preferred order before clicking Merge.
Will bookmarks and hyperlinks be preserved?
Internal page content, text, vectors, and layouts are completely preserved during concatenation.
Are my business contracts kept secure?
Yes. Merging happens entirely within your web browser. No document data is ever transmitted to or stored on external servers.
What happens if one of my PDFs has different page sizes?
Our merger preserves the individual page dimensions of each document, so an A4 page and a US Letter page will both keep their original dimensions.
