Entitled to a free upgrade? Owners of Nitro PDF
Professional version 4 who purchased Nitro PDF Professional after January
1, 2007 can upgrade to the latest version free of charge. After downloading
the installer, you will need to obtain an upgraded serial number from
this page.
Considering switching to version 5? Nitro PDF Professional 5
introduces a major revision to the application interface that makes
basic PDF tasks significantly easier to access and use. However, some
established or expert users may prefer the classic version 4 interface.
If you're not sure which you'd prefer, we recommend you install Nitro
PDF Professional 5 side-by-side with your existing software. You can
explore the new interface in trial mode without restriction for fourteen
days before committing to the upgrade. Once you purchase the upgrade,
you must uninstall the previous version.
