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.
What is Lumin vs Lumin Tools?
Lumin Tools is a sub-site of Lumin hosting more advanced editing features such as the PDF Unlocker tool, OCR reader, Convert, Compress and more. Both sites are completely free to use.
Can I just unlock a PDF and go?
Yes, absolutely. You need to create a Lumin Tools account, but it’s free and easily done. You’ll have a range of other PDF features at your disposal too, should you choose to explore them.
Can I lock a file?
No, Lumin only allows you to unlock files. However, we do offer a secure platform for sending and sharing files as well as the Compress tool for downsizing larger files to avoid corruption.
