Overview
Lumin replicates traditional paperwork with modern tools. Its full digital toolkit allows you to highlight and make notes on files, as well as level up with real-time collaboration on documents. 

Upload and edit reports, presentations, spreadsheets and more – you can even add your signature documents so they’re ready to be sent off into the wider world. Lumin also has more heavy-duty PDF editing capabilities, so you can convert, split or merge files to get those reports in shape.

Lumin integrates seamlessly with the storage platforms you know and love. View your files or email attachments without downloading them – just right-click any file and select ‘Open with’, then ‘Lumin PDF’. 

All your edits can be automatically synced back, so you don’t lose a thing.

Gone are the days of manually printing and scanning documents. Lumin is the bridge between paper and the cloud.

Use it on your browser or download the desktop app here: https://www.luminpdf.com/download/

Key features include:
- Comment on, edit text, or add signature to PDF documents.
- Insert images, shapes and text
- Merge, split or extract pages from PDFs
- Create Teams and Circles to collaborate with a bit more organization and siloing
- Communicate in real-time
- Share documents with anyone, anywhere, anytime
- Download the desktop app and work offline
 
Designed to feel like second nature, Lumin is a great entry point into cloud-based work. We’re ready when you are.

It was a little confusing at first cause I dont know all of the google controls yet. But once i got the hang of it, i was very happy with the controls. Definitely using this again.
