JPEG To PDF With Imagemagick

ImageMagick is an awesome toolkit with several powerful features for image creation and manipulation. You can use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bezier curves. Here, I will show how you can use ImageMagick suite to convert JPEG to PDF quickly.

First make sure imagemagick suite is installed in your system.

Ubuntu/Debian
$ sudo apt-get install imagemagick


CentOS/Fedora
$ sudo yum install imagemagick


Below are some of the examples of using convert which is a part of ImageMagick to convert Jpeg to PDF.

Single Image
$ convert image.jpg image.pdf


Multiple Images
$ convert 1.jpg 2.jpg 3.jpg output.pdf


Resize and Convert
$ convert -resize 80% image.jpg image.pdf


Negate and Convert
$ convert -negate image.jpg image.pdf


You can actually use different available switches to get your output as expected. I usually use PdfTk in conjunction with this technique to work in different scenarios and it really works great. I hope this helps :)
