Files never leave your device — merging runs locally on your machine.
Merge PDF
Combine several PDF documents into a single file. Reorder them as you like — all processing happens in your browser.
Reorder
Arrange the documents with the arrows before merging them in the order you want.
No limits
No watermark, no size cap beyond your browser memory, no account.
Frequently asked questions
Are my files uploaded anywhere?
No. Merging runs entirely in your browser with JavaScript. No file is ever sent to a server.
Is there a limit on the number of files?
We impose no limit. The only constraint is your browser’s available memory for very large documents.
Can I change the order of the files?
Yes. After selecting them, use the up/down arrows to arrange them. They merge top to bottom.
Is quality preserved?
Yes. Pages are copied without re-compression, so text and images stay exactly as they were.
