Frequently asked questions
Can I change the order of the files?
Yes — use the up and down arrows to set the order they'll appear in the final PDF.
Is there a limit to how many PDFs I can merge?
No fixed limit, though very large combined files may take a moment to process.
Do password-protected PDFs work?
Encrypted PDFs generally can't be merged until the password is removed first.
Are my files uploaded to a server?
No — merging happens entirely in your browser using an open-source PDF library.
