Frequently Asked Questions

How many PDFs can I merge at once?
There is no fixed limit. You can merge as many PDFs as your browser memory allows. Most devices handle 10–20 PDFs comfortably.
Can I reorder pages before merging?
Yes. dShift lets you drag and reorder files before merging, giving you full control over the final document order.
Are my PDFs safe?
Completely. Merging is done locally in your browser using pdf-lib. Your files are never uploaded or stored on any server.
Does dShift support password-protected PDFs?
Currently, dShift works with unprotected PDFs. Support for password-protected files is on the roadmap.
