Do my files get uploaded?

No. Previews are rendered and the merge runs entirely in your browser, on your own device. Your PDFs never leave your computer and never reach a server.

Can I control the order?

Yes. Each file shows a thumbnail so you can tell them apart. Drag a row to reorder it, or use the up and down arrows. They are combined in exactly the order shown on screen, top to bottom.

Are the pages changed in any way?

No. Each page is copied exactly as it was — same text, fonts, and layout. Nothing is re-rendered or re-compressed.

What if one file isn't a valid PDF?

The merge stops and tells you which file is the problem — for example a password-protected or damaged file — so nothing is silently dropped.

Merge PDF

Combine several PDFs into one, in the order you choose. See a preview of each file, drag to reorder, and merge — entirely in your browser. The files are never uploaded. No account, no email.
