Question 1

Are my PDF files uploaded to a server?

Accepted Answer

No. All merging happens locally in your browser using the pdf-lib library. Your files never leave your device.

Question 2

Is there a limit on the number of PDFs I can merge?

Accepted Answer

There is no fixed limit. The practical limit depends on your device's available memory. Most users can merge 50+ files without issues.

Question 3

Can I reorder pages before merging?

Accepted Answer

Yes. After dropping your files, you can drag them into the order you want. The merged PDF will follow this order.

Question 4

Will the merged PDF keep bookmarks and links?

Accepted Answer

Basic page content, images, and text are preserved. Interactive elements like bookmarks and form fields may not carry over in all cases.
