Frequently asked questions
Are my files uploaded?
No. The PDFs are merged with JavaScript directly in your browser; nothing is sent to a server.
Is there a file or page limit?
There is no fixed limit; very large files depend on your device's memory.
Are bookmarks and form fields kept?
Pages, text and images are kept. Bookmarks and interactive form fields may be lost when merging.
