Merge PDF
Combine several PDFs into one, in the order you choose — merged in your browser, never uploaded.
Part of PDF tools.
Merged in your browser, not on a server
The files you drop here are read by your own browser and combined in memory with pdf-lib; the merged PDF you download was produced on your machine. Nothing is uploaded, which matters for the documents people usually merge — contracts, statements, scanned forms — and you can check it by opening the network tab while you merge.
Choose the order before you merge
Each file appears as a card with a preview of its first page. Drag the cards, or use the arrows, to set the order: the pages of the first file come first, then the second, and so on. Pages are copied as they are, so text stays selectable and nothing is re-compressed.
Password-protected and damaged files
An encrypted PDF cannot be combined without its password, so it is refused with a message naming the file, and the other files stay loaded. Remove the protection in the app that set it, then add the file again. A damaged file is reported the same way instead of breaking the merge.
