What our customers are saying

Once again to circle back. I’m really enjoying the toolkit, after getting more and more familiar the methodologies are consistent and becoming predictable. Speed, ability, quality and memory management seem to be spot on especially compared to some imaging toolkits I’ve used over the last 25 years. Thank you to the developers, testers and support folks you have made my work a lot easier than I hoped… Read the full testimony

Our Happy Customers

SO THE WINNER IS….. : GdPicture –[…]. GdPicture installed quickly, and a test app could be produced easily. Performance was fantastic. Best of all, it did not get in the way of our interface, a simple container that allowed me to add the buttons and functionality required on the form. If it’s just PDF viewing you want then the $950 license is one of the most economical on the market, if you want what seems to be one of the most powerful image manipulation toolkits around then the ‘Ultimate’ combination is by far the best value for money.

.Net PDF Viewer showdown

I spent several months downloading trial sdks, utility apps, etc. None of the utility apps were flexible enough to meet our needs. Several of the SDKs were suitable, but none of them were as fast and accurate and reliable as GdPicture.NET.



While GdPicture’s functionality and performance is impressive, what has really set them apart for me is their service. My application frequently processes legal documents around 5,000 pages, which creates unique challenges that I doubt many of their other customers face, and the few times I’ve had an issue they’ve immediately responded with a fix within days. It’s very refreshing to work with a company that actually cares about its users, and I greatly appreciate and admire Loic, Elodie and the rest of the GdPicture team’s work.



I just wanted to say how happy I am with this product and your service. I’ve had a couple things I needed that I couldn’t figure out how to make happen and within a couple days of notifying you on each instance, you had an update for me. The more I get into this control and see what all it can do, the more excited about the possibilities I become. Keep up the great work! I wish many other developers and support staff would take lessons from you guys.
