New · Shared links with expiry

Your files, safe and in sync — on every device.

Cumulo keeps photos, documents and big project folders encrypted in the cloud, so you can open them anywhere and share them with a single link.

No credit card required. Cancel anytime.

Everything you need to keep work moving

Changes appear on all your devices within seconds, even for multi‑gigabyte files, thanks to block‑level transfer.

Send a link instead of an attachment. Set a password, an expiry date, or make it view‑only.

Restore any file to an earlier version from the last 30 days. Deleted something? It stays in the bin until you empty it.

Files are encrypted in transit and at rest. Turn on two‑factor sign‑in for an extra layer of protection.

Mark folders as available offline and keep working on the plane or the train. Everything catches up later.

Open documents in your favourite editor, drag files from the desktop app, or upload from the browser.
