Your files never leave this device

Most PDF sites upload your document to their servers to process it. Plume doesn't have that step. The tools run entirely inside your browser tab.

Processed locally in your browser
Your PDF opens in the tab and stays there. Processing happens on your own machine.
Works offline after first load
Airplane mode? The tools still run. The whole app caches on your device.
No account or cloud storage
Nothing to sign up for and nowhere for your files to sit. Close the tab, everything is gone.

Why we built Plume

PDF tools shouldn’t ask you to hand over private documents just to rotate a page. So Plume runs where your files already are, right on your device, and the tools stay free, unlimited and watermark-free.

Three things Plume will never do: upload your PDFs to a server, put a watermark behind a paywall, or make money from what is inside your files. If that ever changes, hold me to this paragraph. Written July 2026.
