its unusable for me..
i need real 1:1 image-extraction..
not a fixed resolution

if i use 72dpi... most image to small an extraction mean lost of data
if i use 150 or 300 dpi. most image to big an saving of images ar bigger then pdf
and sometimes the images have non-standard resolution
and produce moire-images....

VERY UNUSABLE....

that the reason i have test dozens of pfd-extraction-tools
and i have found only PDF-Tools give me 1:1 extraction
but its slow.. and cache the images as PNG before i convert it to webp
results in gig of space...

it was usable if i set 300dpi and a filter of XNConvert
could analyse the image real resolution an resample this back....

I installed Ghostscript http://mirror.cs.wisc.edu/pub/mirrors/g ... 902w64.exe
But XNView says "not an image" if I choose a pdf as input file.

I'd like to convert one pdf to multiple JPEG files with auto crop of white margins. I hope this is possible.

"Image extraction" from PDF is not a conversion from PDF to Image. It uses only the images in the PDF - if there are some ...

If you need only to crop a PDF: http://noliturbare.com/pdf-tools/pdf-cropper

OK, XNConvert is the wrong software for this. No, I need to convert a pdf to multiple jpeg files plus they should be auto cropped.
PDFCreator printer driver can export to jpeg or better tif, but leaves ugly white borders. XNConvert can do the auto crop step then. 2 steps, but anyway this would work.
