    A few useful answers

    Can I change the document order?

    Yes. Move a file up or down before merging. Pages within that file keep their original order.

    Will this change my original PDFs?

    No. LM Tools creates a new PDF for you to download. Your original files are not modified.

    Are my files uploaded?

    No. This tool processes files in your browser. Leaving or refreshing the workspace clears its in-memory files and downloads.

    Can I merge a password-protected or signed PDF?

    Not in this version. Use a regular, unencrypted, page-only copy when appropriate. This tool does not remove protection or preserve digital signatures.
