    Answer-first introduction

    Add two or more PDF files, arrange them in the order you need and export one combined document. Toolistify should show the number of files, total pages, estimated output size and verified privacy behavior before the merge begins.

    Merged successfully: [number] files, [number] pages, [size]. Review the downloaded document before sharing it, particularly page order, orientation, form fields, signatures and bookmarks.

    How to combine PDFs

    1. Add the PDF files.
    2. Review file names and page counts.
    3. Arrange the files or pages.
    4. Remove duplicates or unwanted documents.
    5. Merge and download.
    6. Open the output and check that every page is present.

    What may change during a merge

    Depending on the library and files, interactive forms, digital signatures, bookmarks, attachments, comments, encryption and accessibility tags may not be preserved. The page should list tested behavior rather than saying that every feature remains unchanged.

    Password-protected PDFs

    Explain whether encrypted files are unsupported, require a password locally or are uploaded for processing. Never request or log a document password unnecessarily.

    FAQs

    Can I reorder individual pages?

    Answer yes only when the tool genuinely supports it; otherwise say that files can be reordered as complete documents.

    Will merging invalidate a digital signature?

    Modifying a signed PDF can invalidate or remove signature validity. Warn users before processing signed documents.

    Are files stored after merging?

    Publish the verified implementation and retention details.

    Can I merge very large files?

    Show actual browser or server limits and a clear error before a long upload fails.
