    Frequently asked questions

    Is it safe to merge private documents here?

    Yes. The files are combined inside your browser and never sent to a server.

    Can I merge password-protected PDFs?

    No. Remove the password first using the program that created the PDF, then merge it.

    Is there a file size limit?

    There is no set limit, but very large files depend on your device's memory. Most documents merge in a second or two.
