    How do I merge PDFs?

    Choose at least two PDFs, arrange them in the desired order, and select merge. Pages are copied in the order shown.

    Are my PDFs uploaded?

    No. Tooloo uses pdf-lib to read and merge files in browser memory without sending them to a backend.

    Current limitations

    Password-protected PDFs are not supported. Large or complex documents may be limited by your device memory.

    Does merging reduce PDF quality?

    The merge copies existing PDF pages without intentionally recompressing images. Some specialized PDF features may not be preserved.
