You will need to choose the right edition: if you want to test PDF Reducer, download the Cloud Edition.

The On-Premises Editions of PDF Reducer are distributed in two versions: one for desktop and one for server. If you need to use PDF Reducer On-Premises Edition on a single computer, the Desktop version is for you. Companies and organizations that want to use PDF Reducer on one server machine can choose the Server version.
The download package of the On-Premises Edition includes a 30 days free trial. The free trial starts at the first use of the software. When the trial expires you will need to enter a commercial key to keep using the product. If you need an extension of the evaluation, please send us a message here and we will send you a trial key. The free trial will cause your pages to have a watermark on them. When purchasing the On-Premises Edition your pages will no longer be watermarked upon compression.
Owners of a commercial edition can contact the technical team and get priority support by opening an account on the Helpdesk.
