Frequently asked questions

How do I merge PDF files online for free?

Upload two or more PDFs to the merge tool above, drag them into the order you want, then click “Merge PDF”. Your combined file downloads instantly — no account needed.

Is there a limit to how many PDFs I can merge?

There is no fixed limit. Merging happens in your browser, so very large files are limited only by your device's memory.

Will merging change my PDF quality?

No. Pages are copied into the new document without re-rendering, so text, images and quality stay exactly the same.

Are my files uploaded anywhere when I merge PDFs?

No. The merge happens entirely in your browser with client-side technology. Your files never leave your device.

Can I change the order of the PDFs before merging?

Yes. After uploading, drag any file card up or down to reorder. The merged PDF follows that exact order.
