    PDF Perfect combines PDF files inside your browser. Add two or more PDFs, drag them into order and download one merged document. The files are not uploaded to PDF Perfect; the practical file count depends on their combined size and your device's memory.

    How to merge PDF files

    1. 1

      Add your PDF files

      Drag two or more PDFs onto the drop zone, or click it to choose files from your device.

    2. 2

      Put them in order

      Drag the files in the list into the order you want them to appear in the merged document.

    3. 3

      Merge and download

      Click Merge and download your combined PDF. No account needed.

    What the merged PDF keeps

    Pages are copied across exactly as they are, so text stays selectable, images keep their quality and page sizes are unchanged. Files appear in the order shown in the list, and each file's pages keep their original order.

    Need to drop a few pages first? Use Extract PDF Pages on each file, then merge the results.

    Is it safe for confidential documents?

    PDF Perfect has no PDF upload endpoint. The merge happens in JavaScript on your device, and your browser creates the download without sending the PDF file or its contents to PDF Perfect.

    The website still makes ordinary requests for pages, fonts, analytics, feedback you submit and, when enabled, advertising. Open your browser's Network tab while you process a file to confirm that none of those requests carries the PDF.

    How to check that your file never leaves your device

    Limits

    • The file picker accepts each PDF up to 1 GB. The total you can actually merge depends on your device's available memory and may be much lower.
    • Password-protected PDFs aren't supported. Remove the password first.
    • Bookmarks and form fields from the original files may not carry over.
