(Thanks to for suggesting an update hinting at these new features of pdfimages. Update: Recently, Microsoft is making a change to its Microsoft Office branding. It also gives the actual size of images in terms of storage ( 'size') and their compression ratios ( 'ratio'). The new output format additionally shows the respective horizontal and vertical resolutions for each image ( 'x-ppi', 'y-ppi').

In order to calculate the DPI, you'll have to measure the width/height of the image as it is displayed on the page (you can do that with one of the tools in Acrobat/Reader) and then use the respective info from the above output to calculate the DPI. (This is what plinth's comment to his own answer also emphasizes.) If a large raster image is squeezed into a small space on the PDF page, your DPI value would be quite high. This however does not (yet) give you any clue about the DPI. Note again: this version of pdfimages is the one from Poppler (the one from XPDF does not (yet?) support this new feature).Īs you can see this lists the respective widths and heights of the images.

Raster graphics which are preserved inside a PDF as such cannot be extracted by pdfimages. If you extract this, you'll not get your vector graphics back, but a raster image. Even if the original file which was converted to PDF included vector graphics, then the converter program could have decided that it includes these as raster image. There's no such thing as a 'vector image'. First, what in PDF parlance is called an 'image', by definition always is a raster image.
