    Runs entirely in your browser. Your data isn't uploaded — this page makes no network request with anything you type or upload, which you can verify in your browser's network tab. How this works.

    What is the PDF Merger?

    A PDF merger combines several PDF files into one document — the signed contract and its annexures, a month of receipts for an expense claim, the chapters of a report. Add the files, put them in the order you want, and download a single PDF with every page of every file.

    Most online mergers upload your documents to a server to do this. This one does not: the files are read and combined inside your browser tab, so contracts, bank statements and ID documents never leave your device. Pages are copied exactly as they are, so text stays selectable and nothing is re-compressed or watermarked.

    How to use it

    1. Drop two or more PDFs onto the page, or click to choose them.
    2. Use the arrows to put the files in the order they should appear.
    3. Press Merge PDFs. The page count of each file is shown so you can check the total.
    4. Download the merged PDF.

    Example

    Three files combined in the order they were arranged.

    Files, in order
    1. contract.pdf        4 pages
    2. annexure-a.pdf      2 pages
    3. id-proof.pdf        1 page
    Result
    contract-merged.pdf   7 pages
    
    pages 1–4  contract.pdf
    pages 5–6  annexure-a.pdf
    page  7    id-proof.pdf

    Frequently asked questions

    Are my PDFs uploaded anywhere?
    No. The PDF engine runs inside the page, and the files are read from your device with the browser’s File API. You can disconnect from the internet after the page loads and merging still works.
    Will merging reduce the quality of my PDF?
    No. Each page is copied into the new document as it is — text, images and vector drawings are not re-rendered or re-compressed.
    Can I merge password-protected PDFs?
    Not while they are locked. Open the file with its password, save or print an unprotected copy, and merge that. The tool tells you which file is protected rather than producing a broken result.
    Is there a size limit?
    There is no fixed limit, but everything happens in your browser’s memory, so very large files (hundreds of megabytes in total) are best merged on a desktop browser rather than a phone.
