Frequently Asked Questions
Does Docukit upload my PDFs to a server?
No. Merging happens entirely in your browser. Your files never leave your device.
How many PDFs can I merge at once?
Up to 50 PDF files. For very large batches, we recommend splitting into groups if you notice memory warnings.
Can I reorder pages from different PDFs?
Yes. Every page of every file is shown in the order it will be merged, marked with a letter for the file it comes from. Drag any page to a new place, even between the pages of another file, or press × on a page to leave it out. "Reset order" puts the pages back in file order.
Are encrypted PDFs supported?
Yes. A password-protected PDF gets a password field in its row. Once you enter the password its pages appear and can be arranged like any others.
