Frequently Asked Questions
1. Are my PDFs uploaded to a server?
No. All PDF processing happens 100% in your browser using the PDF-lib JavaScript library. Your files never leave your device, ensuring maximum privacy and security for sensitive documents.
2. Can I merge password-protected PDFs?
Currently, password-protected PDFs cannot be processed by this tool due to encryption. You must remove the password protection using a dedicated PDF editor before merging or splitting them here.
4. Is there a page limit for merging PDFs?
There is no hard page limit, but extremely large merges (thousands of pages) may depend on your browser's available memory. For most professional and personal use cases, the tool handles merges smoothly.
