Support ZiruPDF
ZiruPDF is free. Donations are entirely optional and never affect any feature.
Why accept voluntary donations?
Every ZiruPDF feature is free: no usage limits, no watermarks, no ads, and the core document processing happens on your computer.
If ZiruPDF has saved you time, voluntary support for continued development, testing and maintenance is welcome. A donation is not a purchase and does not unlock extra features.
Entirely optional
You can keep using all of ZiruPDF without donating. We never ask for donations through start-up pop-ups, exit reminders or feature limits.

Donation options are being prepared. Official ways to support the project will be announced on this page.
Please use only the official donation options published on zirupdf.zirulab.org, and do not pay through QR codes or links of unknown origin.
Transparency
- ZiruPDF is free for personal, educational, business and commercial use.
- Donating does not change the software license and gives no extra features or priority rights.
- Donation links open only when you click them; ZiruPDF never uploads documents because of the donation feature.
