Merge PDF
Combine multiple PDF files into one, in any order, directly in your browser.
Combining several PDF files into a single document — merging a set of scanned contracts, joining chapter files into one manuscript, or assembling a batch of invoices into one report — is one of the most common document tasks, and one of the most annoying to do without the right tool, since most operating systems have no built-in way to merge PDFs at all.
This merge tool runs the entire operation in your browser using a real PDF processing library, not a server upload — your files never leave your device. Drop in two or more PDFs, drag them into the exact order you want using the up/down controls, and click Merge to download a single combined PDF instantly. Because processing happens client-side, there's no file size limit imposed by a slow upload connection, and no risk of your (possibly sensitive) documents sitting on a third-party server.
The merge preserves each source PDF's pages exactly as they are — text stays selectable, images stay full quality, and page order in the output matches the order you arranged the files in before merging.

Frequently asked questions
Common mistakes to avoid
