Frequently Asked Questions

Are my PDF files uploaded to a server?

No. PDF processing happens entirely in your browser using the pdf-lib library. Your files never leave your device.

Is there a page or file size limit?

There is no enforced limit. However, very large PDFs (100+ MB) or documents with many pages may take longer to process depending on your hardware.

Can I merge password-protected PDFs?

Password-protected PDFs cannot be merged or extracted without first removing the password. The tool currently does not support unlocking PDFs.

What order are PDFs merged in?

PDFs are merged in the order they appear in the upload list. You can drag and reorder the files before processing.
