This app is amazing! We use lemonink to watermark sell ebooks and audio downloads and it works perfectly for us. The interface is easy to use and very intuitive and the customer service is top notch!

A fine selection for any digital offering. The setup unfolds with ease, requiring little more than a moment’s attention, while the support behind it stands attentive and unwavering. Once the purchase is complete, a tastefully watermarked file appears seamlessly within the client’s dashboard—an elegant touch that completes the experience. My sincere thanks once again.

This is perfect for our digital cookbooks! Easy install and customer service is fantastic. The buyer receives a beautiful PDF with watermark right away to their inbox. Thank you again!

Lemonink has suited our needs perfectly and every single step of installation was straightforward. Support has been great too.

The LemonInk team are terrific to work with. This app works exactly as described and is a low-cost way to include social drm protection for digital items. We wanted a few customizations to how the app works and where the watermark is placed and Piotrek from LemonInk helped us every step of the way. He is incredibly responsive to questions and requests and just really nice. I highly recommend this app.

Easy to use. Love it.

We started using lemonink to sell our e-books. We were able to batch map a large number of e-books from support, which was very helpful because we were able to sell e-books immediately and not lose any opportunities!

We are really happy with LemonInk which answers perfectly our needs in terms of protection for our digital products. Moreover, the team is super helpful and answered quickly to our questions. Definitely recommend !
