Frequently Asked Questions

  • Is Lumin free?

    Sure is! Though we do have options for people and businesses wanting to unlock all our features – such as unlimited storage and certain tools only available to Professional users – you can try Lumin Professional free for 7 days, or stay on a free plan. Discover our plans here to learn which one is the right fit for you.

  • How do I use Lumin?

    Lumin works on your browser, or you can download our desktop app and keep Lumin handy on your computer. We’ve also got a mobile and tablet app which includes our most popular features.

  • Can I just sign a document and go?

    Yes, absolutely. You do need to create an account in order to use Lumin, but it’s easily done and you’ll be accessing the eSignature function in no time. You’ll have a range of other PDF features at your disposal too, should you choose to explore them.

  • Can I send a document for signing?

    You can share documents using Lumin but the recipient will need to create a Lumin account in order to sign it. If you’re looking to purely sign and send contracts and documents, check out our sister company Bananasign where you can send from either your browser or mobile. The receiver doesn’t need a Bananasign account to sign the document.
