Frequently asked questions

  • Are Lumin’s tools free to use?

    Lots of them are, yes. 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.
  • Can I combine PDF files with Lumin?

    Yes. You can use Lumin’s Merge tool to combine PDFs. You can also split PDFs in half, extract or delete pages from them, and put PDF pages in a new order.
  • Can I convert a Word document into a PDF?

    Yes! We have a Convert tool that allows you to turn other Word, PPT, Excel and JPG files into PDFs.
  • Can I use Lumin’s tools while offline?

    Yes! While Lumin is designed for the cloud, we know sometimes work happens from the ground. Just switch on “offline mode” and continue editing your document. When you next connect to the internet, your edits will be saved. Learn more here.
  • How much can I edit for free?

    You can edit PDFs as much as you like. It’s only completing a document – that is printing, scanning, syncing or downloading a document – that will count towards your limit of 3 documents per month on the free plan.

    Our paid plans enable you to complete much more.
