I use imagemagick to convert pdf to jpeg for thumbnail images from a good quality pdf.
The resulting jpeg image is poor in quality.
Please advice how to get rid of this issue with any settings.

See the millions of postings on these forum about PDFs. You probably haven't provided a suitable "-density" setting, eg
Code: Select all
convert -density 600 in.pdf out.jpg

Hi snibgo,
Thanks for your quick response, i will check on these.

You can trim off the white border. Then, if you want, add another border:
Code: Select all
convert -density 600 in.pdf -trim -bordercolor Pink -border 10x10 out.jpg

Sometimes pdf is proper with one full page, but the thumbview of pdf has two page sections with one is blank and other side with content.
When we convert jpg the thumb view of pdf is converted with half page blank, but we need the original pdf to be converted as jpg. please advice how to get ride of this issue.

I don't understand the problem. Can you post an example PDF? Put it on a free site such as dropbox, and copy the link here.
