Frequently asked questions

  • Is Lumin free?

    Sure is! Lots of our tools are free. You can draw on PDFs, comment on them, add text, signatures and images; all the basics are covered.

    Our paid plans expand your toolkit: you can edit PDF text, redact information, create fillable fields and much more. Discover our plans 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.

  • What are Circles?

    Circles are shared spaces in Lumin for you to store and edit documents your whole team uses. This makes it easy for you to work in real-time with your colleagues, classroom or clients. You can add as many people as you like to your Circle, and create Teams inside it to separate your work into silos. Learn more about Circles.

  • Can I have more than one Circle?

    Yes. You can create Circles for your family, your work, your fantasy football league; whatever you like. And you can join as many as you want, too. But you might not need to: inside your Circle you can have Teams, where more niche work gets done.

  • Can multiple people work on a PDF at the same time?

    Yes! There is no limit on how many people can work on a PDF – but it might get a bit chaotic if you get the whole company in at once! You can make your colleagues ‘editors’ if you want them to make changes, or just ‘viewers’ if you’d prefer to keep their interference minimal.
