Can I read a PDF on mobile?

Yes, absolutely. Lumin has a desktop, mobile and tablet app that syncs all your files and updates so you can pick up where you left off. Our app is compatible with both Apple and Android devices.

Can I read a PDF while offline?

Yes! While Lumin is designed for the cloud, we know sometimes work happens from the ground. Just switch on “offline mode” and continue editing your document. When you next connect to the internet, your edits will be saved. Learn more here .
