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.
