When converting a PDF file, the embed bitmap images are systematically
converted to PNG.
This strongly increases the filesize.

Is there any way to preserve the JPEG format ?

PDF2SVG checks at the compression format of the source image. If the
image is using DCTDecode it will try to pass it through as JPEG,
otherwise it will use PNG. Converting everything to JPEG could
possibly degrade image quality. Please let us know if you ran into any
cases where JPEG images are not properly preserved or if you notice a
significant increase in file size.

Just to let you know, it seems that the JPG format is preserved only
for RGB images. CYMK jpg images are converted to PNG.

I beleive that SVG is not supporting CMYK JPEG. Also the CMYK support
is not properly implemented in most viewers. We will add option to
convert CMYK to RGB JPEG.
