Switching from Acrobat Pro
Open Madosuite
In your browser. The PDF app starts on your own device; nothing is installed.
Bring your files
Upload your .pdf files in Files. They stay in the browser on this device.
Keep the format
PDF saves PDF, PNG pages, DOCX (layout is lost), so a file can go back to someone who still uses Acrobat Pro.
