Frequently asked questions
Are my PDF files uploaded to a server?
No. Your PDFs are processed entirely inside your browser and never leave your device — ideal for contracts, invoices and other confidential documents.
How many PDFs can I merge?
As many as you like. Because everything runs on your device there are no upload limits.
Will the quality change?
No. Pages are copied as-is, so text stays selectable and images keep their original quality.
Can I merge password-protected PDFs?
No. Remove the password in your PDF reader first, then merge the unlocked file.
Is there a file size limit?
There is no fixed limit because nothing is uploaded. Very large files (hundreds of MB) depend on your device’s memory; a desktop browser handles them best.
