XnView Software

We have a number of PDF files that we are converting to PNG for use on our website. When using our PDF program (PDF Professional Converter) we can select the resulting resolution of the PNG and get optimal results. However, when we use XnVIEW to perform the conversions (individual or batch), the conversion dialog offers no option for effectively specifying a resulting resolution that helps the text.

Worse yet, whatever resolution XnVIEW is defaulting to is producing a poor image with course text that is hard to read. We also tried specifying a DPI value on the 'Transformations' tab of 300 dpi in the conversion dialog. This creates a huge file, but the resolution of the text is not any better. Does anyone know how to control the resulting resolution of the text in the PNG file when converting from PDF to PNG? (PDF Converter can do it, so XnVIEW should also)

What are the DPI settings in "Options - General - Read/Wrtite - Read EPS/PS/AI/PDF"? Try the conversion with a higher value ...

A workaround would be getting XPDF and then extracting all bitmaps from PDF using PDFimages and then converting them back to PNG with XnView.

Thank you Peter, you resolved the problem for us! We had no idea that the conversion program was also modifying the SOURCE document as an INPUT. Our focus was all over managing the output. We understand the program a little bit better now, thank you again for your insights.

Your welcome. Some month ago I had the same problem ...

Alternatively, use PDFDRAW tool from MUPDF
