Hello is it possible to improve the duration of conversion of jpegs with HTML5 uploader. It takes around 5/6 seconds to convert a 6Mo JPEG HQ file to a small one (around 120Ko) my proble is that I need to convert and upload thousands of HQ jpegs and with HTML5 version the global conversion time increase a lot with the JAVA version the conversion time was quite good ... Hope you understand my problem and could help me best regards

I afraid working with images in pure JavaScript will never be as fast as the native code of ActiveX (or even Java). JavaScript was not made efficient for the memory-intensive operations such as image processing algorithms. So you can follow certain guidelines to improve the speed (say, don't use the "high" ResizeQuality mode), but if it does not help, we have nothing to do with it. You can also try uploading the source files and generate the reduced copies on the server, however, in this case, the amount of data will be increased and the overall upload speed may be worse. So it will help only for slow devices.
