Frequently asked questions
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser, so your documents never leave your device. That makes it safe for contracts, tax forms and medical records.
Is there a limit on files or pages?
There is no fixed limit. Very large files use more memory, so on an older phone it's best to merge up to a few hundred pages at a time.
Will the quality of my PDFs change?
No. Pages are copied exactly as they are — text stays selectable and images are not re-compressed.
Can I merge password-protected PDFs?
Not directly. Open the PDF with its password and save a copy without protection first, then merge that copy.
How do I change the order of the files?
Use the up and down arrows next to each file, or press “Sort by name” to order them alphabetically.
