Merge PDF
Combine several PDFs into a single file, in the order you choose.
Runs 100% in your browser — your PDFs are never uploaded or saved anywhere.
Drop your PDFs here
or choose files from your computer — two or more PDFs.
Drag a card to reorder, or use the arrow buttons. Files are merged top to bottom.
Reading PDFs…
Private by design
Everything happens locally in this tab. Your files are never sent to a server.
Fast, even at scale
Merge dozens of many-hundred-page PDFs in seconds without freezing the tab.
Free, no install
No account, no upload limits, nothing to download. Just open the page and use it.
100% in your browser — nothing is uploaded, nothing saved to disk.
