Frequently Asked Questions

Is there a limit on file size?

There is no strict limit! Since we don't upload your files to a server, you can usually merge very large documents as long as your computer has enough memory to handle them.

Can I reorder pages inside the files?

This tool joins whole files together. If you need to move, remove, or rotate specific pages inside a file before merging, please use our PDF Organizer tool first.

Are my files safe?

Yes, absolutely. We don't see your files. They stay on your device the whole time and are processed by your own browser.

Can I merge PDFs on my phone?

Yes! NanoZipt works great on phones and tablets. You can combine PDF files directly on your iPhone, iPad, or Android device without installing any apps.

What if my PDFs are different sizes?

No problem. Our tool keeps the original size and shape of every page. You can mix A4 pages with Letter pages or portrait with landscape, and they will all be saved correctly in the final file.
