Frequently asked questions
Are my documents uploaded to a server?
No. Merging happens inside your browser, on your device. Documents, contracts, college papers — nothing leaves your computer.
How many PDFs can I merge at once?
Up to 20 files per round, with a maximum of 100 MB each. Need more? Just merge the result with the next batch — no limit on rounds.
Can I choose the order of files?
Yes. Drag files up or down in the list (or use the arrows). The order in the list is the order in the final PDF.
Does it work with password-protected PDFs?
No — password-protected PDFs can't be read without the password. Remove the password in the program that created the file and come back.
Does the final PDF lose quality?
No. Pages are copied as-is, without recompression — text, images and formatting are identical to the originals.
