About this tool
Merging combines several PDF files into one document, keeping every page in the order you set. It is the quickest way to turn a stack of separate exports — invoices, scans, chapters — into a single file you can send or archive.
This tool merges entirely in your browser. The files are read into memory, combined and offered back for download; nothing is uploaded to a server.
How to use it
- Add two or more PDF files by dropping them in or browsing.
- Drag the arrows to reorder — the top file becomes the first pages.
- Click Merge PDFs.
- Download the combined document.
Common problems
- The pages came out in the wrong order.
- Order follows the list top-to-bottom. Use the up/down arrows on each file to arrange them before merging.
- A password-protected PDF will not merge.
- Files locked with an open password must be unlocked first. Owner-locked (permission) PDFs usually merge; open-password files do not until the password is removed.
