    How to merge PDF files

    1. Choose or drop your PDF files.
    2. Use ↑ and ↓ to set the order. The top file comes first.
    3. Press Merge PDFs. Your combined file downloads straight away.
    Will the text and links still work?

    Yes. Pages are copied as they are, so text stays selectable and the quality doesn't change.

    A file says it is password-protected

    Remove the password first with Unlock PDF, then merge.

    Is there a size limit?

    There's no fixed limit, but very large files (hundreds of MB) can be slow on phones.
