Like cjm suggests, you might want to change the print density. This is the only way to increase quality for vector graphics. If instead, what you want to do is extract embedded images much like gscan2pdf seems to do , guessing the density will usually lead to either quality loss or higher quality than required and waste of disk space.
The answer then is to extract the image rather than print the pdf. See this article which basically advocates the use of pdfimages in order to extract images without quality loss.
As student's answer said pdfimages is a good option. From my experience both gs and convert export to poor quality regardless if you specify the right dpi. But if the pdf has multiple layers per page pdfimages doesn't work and extracts the layers as separate image, in that case best is to use inskcape to export the page as is seen.
First command splits all pages second command converts page by page to png. You can keep them png or just convert them to jpeg. Compared to pdfimages , gs , and ImageMagick's convert I find inkscape 's export the best in quality. Thank you for your interest in this question.

However if I do the following, there is no noticeable quality loss: What is not clear in your questions is whether you talk about text and vector graphics in your pdf, or whether you mean to extract embedded images. Perhaps you need to use -density to do the conversion at a higher dpi: So, try pdfimages -j file.
I'd encourage everyone to try it! What did you misread, and how? Pretty awesome! Solved my day.
Thank you! For example, it took 45 GB of memory to process a book of 6-megapixel pages. It also took about a thousand times longer than pdfimages. Upload a pdf file.

Please fill in the page range if you don't need to convert all pdf pages, you can convert multiple ranges of pages separately. Page range:. Convert your PDF to: Please notice that a higher DPI doesn't mean high clarity of text, when I view an image in DPI on the screen with x pixels, it looks very clear, however, when I view the same image on the screen with x pixels, the image is too large and I have to zoom out it to 50 percent, making the text looks very blurry, the same page in DPI looks perfect on a screen with x pixels.
Specifying a higher DPI dots per inch will occupy more disk space and take more time to download. If the DPI is larger than , you can convert up to pages at a time.
