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.
