Paperstack FAQ
Are my PDF files uploaded to a server?
No. Paperstack processes PDFs and images locally in your browser. Your documents, filenames, and passwords are not uploaded by the PDF tools.
Can I merge a password-protected PDF?
Yes. Enter the PDF password when prompted. Paperstack unlocks a visual copy in browser memory so it can be merged without sending the password or file elsewhere.
Can I reorder, rotate, or delete PDF pages?
Yes. The Edit pages tool shows page previews and lets you drag pages into a new order, rotate selected pages, remove unwanted pages, and export a new PDF.
Does Paperstack add watermarks?
No. Paperstack is free to use and does not add a watermark to merged, compressed, or edited PDFs.
Which file types can I merge?
The merger accepts PDF, JPG, and PNG files. You can arrange them in any order before downloading the combined PDF.
