Frequently asked questions
Is there a limit to how many PDFs I can merge?
No, there is no limit. You can merge as many PDF files as you need. However, extremely large combinations (100+ files or several GB total) may take longer to process depending on your device capabilities.
Are my PDF files uploaded to a server?
No. All PDF merging happens entirely in your browser using JavaScript and the pdf-lib library. Your files never leave your device, ensuring complete privacy and security for sensitive documents.
Can I change the order of PDFs before merging?
Yes! Use the up and down arrow buttons next to each file to rearrange them in your preferred order. The files will be merged in the order shown in the list.
Will the quality of my PDFs be affected?
No. The merging process preserves the original quality of all PDF files. Text remains searchable, images maintain their resolution, and formatting is preserved exactly as in the original documents.
Can I merge password-protected PDFs?
Currently, password-protected PDFs cannot be merged. You will need to remove the password protection from your PDFs before merging them. This can typically be done using PDF reader software if you know the password.
