I am using pdftron.PDF.Convert.ToSvg() to convert PDF to SVG.
One question I face is if there is any option to control the quality of the images/resources extracted from the PDF – the problem I have is that some of the files are big because the PDF has a lot of quality…
If PDF contains large images, you could run ‘pdftron.PDF.Optimizer’ to shrink images prior to conversion to SVG (pdftron.PDF.Convert.ToSvg()).
For an example of how to use PDF Optimizer, please see
In case the problem is not related to images, but slow SVG viewer performance (which is frequently the case), you may want to consider using PDFNet WebViewer (http://www.pdftron.com/pdfnet/webviewer/demo.html) which is using HTML5 canvas for rendering.
