Answer 1

Here you have my solution. Use Imagick directly in your php code.

Convert all PDF pages to JPG

 // create Imagick object
 $imagick = new Imagick();
 // Reads image from PDF
 $imagick->readImage('file.pdf');
 // Writes an image
 $imagick->writeImages('converted.jpg', false);

Convert specific PDF page to JPG

 // create Imagick object
 $imagick = new Imagick();
 // Read image from PDF
 $imagick->readImage('test.pdf[0]');
 // Writes an image
 $imagick->writeImages('converted_page_one.jpg');

Another way to deal with this problem is to use spatie/pdf-to-image library.

Cheers!

Try this.

Answer 5

ImageMagick internally use GhostScript and Generally the conversion of ImageMagick is slow Comparing to Ghoastscript, so If you are only interested on getting convert pdf to images then Ghostscript gs command is faster. below is an sample wrapper around Ghostscript which I wrote few days back.

PDFLib-Php

$pdflib = new ImalH\PDFLib\PDFLib();
$pdflib->setPdfPath($pdf_file_path);
$pdflib->setOutputPath($folder_path_for_images);
$pdflib->setImageQuality(95);
$pdflib->setDPI(300);
$pdflib->setPageRange(1,$pdflib->getNumberOfPages());
$pdflib->convert();
