Volker PostOnline Editor and Project Manager for Internet Presence, Deutsche Bundesbank

The JavaScript engine in PDFreactor is absolutely the best we have seen, based on our market research. Many of the other high-end PDF engines in the market did not support jQuery, AngularJS and chart libraries which PDFreactor fully does. HTML5 made it possible for us to make magazines with special “out of the box” layouts, requested by our clients.

Brian MathorneCTO at Mindworking A/S

PDFreactor benefited our development team through its ease of use and powerful functionality. Practically anything we could conceive and create in HTML5, CSS3, SVG and JavaScript would render flawlessly in PDF. Also the quality and speed of support from the team at RealObjects is very impressive
