How to merge documents of different formats into PDF
While we no longer have to wrangle so much physical paper as part of our day-to-day office work, this doesn’t mean we are finally without difficulties when it comes to storing and sending information. Online documents indeed give us speed and efficiency, especially when it comes to collaborative work; but nonetheless, no one likes to receive an email with 15 documents attached, or a link to a Google Drive folder with disparate information spread throughout a mix of spreadsheets, Word files, and PDFs.Read more How to merge documents of different formats into PDF

Frequently Asked Questions
Is Lumin free?
Sure is! We have options for people and businesses wanting to unlock all our features – such as unlimited storage and certain tools only available to Professional users – but 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.
What are Circles?
Circles is a rebrand of the Lumin feature Organizations, which allows users to create a shared space within their account for convenient document collaboration and editing. This makes it easy for you to join forces with whoever you need to collaborate with: from a colleague at work, to a full classroom of students or your friends and family.
Can I have more than one Circle?
Yes, of course. We know the circles you run in are fluid. You can create Circles for your family, your work, your fantasy football league; 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 I put someone else in charge of my Circle?
Yes, you can transfer ownership of a Circle. Open your Circle and go to ‘Members’. Find the person you want to pass leadership onto and click the three dots next to their name. Select ‘Make Circle Admin’. Now all they need to do is accept your offer!
Can 2 or more 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.
How do I set up a Circle?
To create a Circle, simply head to your profile and select ‘Create a Circle’ from the dropdown list. You will be asked to choose a name for your Circle and upload a file for the thumbnail (a corporate logo or a cute family photo – it’s up to you!). Add the emails of the people you would like to include in your Circle, and hit ‘create’.
