Frequently asked questions
Is my PDF uploaded?
No. pdf-lib runs in this tab. You can disconnect the internet after the page loads and still merge.
Can I merge password-protected PDFs?
Not in this tool. Password files can be opened in PDF to JPG if you know the password, but merge/split/rotate cannot decrypt them.
Are bookmarks and forms kept?
Pages, text, images and most vector art are copied. Bookmarks, some form fields and JavaScript are often dropped — that is a limit of copying pages, not of this site storing your file.
