    About this tool

    This PDF merger runs entirely in your browser using pdf-lib. Drop in two or more PDFs, drag them into the order you want, and click merge — the combined file is built locally and handed straight back to you. Nothing is uploaded, and there is no file count or size limit beyond your device's memory.

    Frequently asked questions

    How many PDFs can I merge at once?

    As many as you like. All merging happens in your browser, so the only limit is your device's available memory.

    Can I change the order of the files?

    Yes. Drag any file up or down in the list, or use the arrow buttons, to set the exact order before merging.

    Are my PDFs uploaded anywhere?

    No. The entire merge runs locally in your browser using pdf-lib. Your files are never uploaded to any server.
