    When merging helps

    Put an application together from separate forms and certificates. Join monthly statements into one file for your records. Combine a cover letter, CV and portfolio before sending them. Bring the chapters of a report back into one document.

    Fast, local and private

    Merging runs on Zaknor's own PDF tools — no AI model is involved and nothing is kept. You can merge up to 10 files of up to 25 MB each, and the files are deleted as soon as the merged PDF is sent back to you.

    How it works

    1. Choose 2 to 10 PDF files.
    2. Arrange them in the order you want with the arrows.
    3. Press Merge PDFs — the combined file downloads automatically.
