Merge PDF
Combine multiple PDF files into a single document. Reorder them before merging — all in your browser.
🔒 100% on-device — your files never leave your browser.
Use Merge PDF as an app
Install it and Merge PDF gets its own icon, opens in its own window without browser chrome, and keeps working with no connection — because it never needed a server in the first place.
Installing copies the tool itself to your device. It adds no accounts, no tracking, and no way for your files to leave your machine.
