Since this is a command line utility, you can access it from PHP using some of the functions to execute external commands.

To convert range of pages, from i to j, use this command: convert 'input_file_name.pdf' 'output_file_name.png' Using with PHP This will actually convert page 2 of PDF to PNG, since numbering starts with 0. convert -density 150 -antialias 'input_file_name.pdf' -resize 1024x -quality 100 'output_file_name-%03d.png'Ĭonvert only specified pages to images: convert 'input_file_name.pdf' 'output_file_name.png' If you include a C-style integer format string, for example if you add %03d to the end of your output file name, you will get output_file_name-001.png, output_file_name-002.png, output_file_name-003.png, etc. If you have more then 10 pages, it would come in handy to have those enumerated file names with multiple digits, for the convenience of easy sorting. etc, will be created in the working directory. Key parameter here is -append which actually makes a difference if PDF is converted to a single image or to a series of images.Ĭonvert a PDF document to a series of enumerated images: convert -density 150 -antialias 'input_file_name.pdf' -resize 1024x -quality 100 'output_file_name.png'Īs a result of this command a series of image files named output_file_name-0.png, output_file_name-1.png, output_file_name-2.png …. Examples:Ĭonvert an entire PDF to a single image: convert -density 150 -antialias 'input_file_name.pdf' -append -resize 1024x -quality 100 'output_file_name.png' ImageMagick is intuitive and it will guess the output format based on output filename extension. In following examples we are going to use -density 150, -quality 100 and -antialias options. Note: It is advisable to use density, antialias and quality options to get the conversion quality that suits your needs. You can convert an entire PDF document to a single image, or, if you like, there is an option to output pages as a series of enumerated image files. Command line tool ImageMagick does that (and a lot more). There is a quick and convenient way to convert PDF to one or more images.
