Combine PDF files into one
Drop in two or more PDFs, drag them into the order you want, and download a single combined file. Everything runs on your device — your files are never uploaded.
Combine PDFs without uploading them
Send one document instead of a stack of attachments. The files are combined in your browser with WebAssembly, so nothing is uploaded — your documents stay on your device.
Order and prune in one pass
Pages keep the order of, and stay grouped by, their source document — no interleaving. Drag to set the document order, and deselect any page you don’t want before you download.
Your files never leave your browser
There's no upload. Everything happens on your device using WebAssembly — the bytes never travel to a server, so your documents stay yours. No ads, no third-party trackers, no accounts. We collect only an anonymous count of how often each tool is used. It's free, and it stays free.
