Frequently asked questions
Are my files uploaded to a server?
No. Merging happens entirely in your browser using your device, so your PDFs never leave your computer.
Is there a limit on how many PDFs I can merge?
There is no fixed limit — add as many as you like. Very large files are limited only by your device's memory.
Will the quality of my PDFs change?
No. Pages are copied exactly as-is into the new document, so text, images and formatting are preserved.
Can I merge password-protected PDFs?
Not directly — remove the password first with the Unlock PDF tool, then merge the unlocked files.
