Convert pdf to jpeg in Linux from command prompt
First you need to have ImageMagick installed in your Linux machine.
To install ImageMagick in Debian, run the following command:
$ sudo aptitude install imagemagick
To convert pdf file to image use the ‘convert‘ command:
$ convert doc.pdf doc.jpeg
convert to tiff
$ convert doc.pdf doc.tiff
If the default output is too low resolution, you can add “-density NNN”, where NNN is a number.
EG: I just did an A4 PDF to a PNG, but it came out too small. To make it bigger/higher res, I did: “convert -density 300 input.pdf output.png”
