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.

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.

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 Lumin’s most popular features.

Can I just compress a PDF and go?

Yes. You need to create an account in order to use Lumin Tools, but it’s easily done and you’ll be compressing files in no time. You’ll have a range of other PDF features at your disposal too, should you choose to explore them.

Why is compressing better than zipping?

When you zip a PDF file and send it from person to person, your files have a higher chance of becoming corrupt along the way. Lumin’s Compress tool is fast, easy and free, saving you time and peace of mind.
