How do I convert a PDF document to a preview image in PHP? [closed]

Answer 1

You need ImageMagick and GhostScript

<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

The [0] means page 1.

Answer 2

You can also try executing the 'convert' utility that comes with imagemagick.

exec("convert pdf_doc.pdf image.jpg");
echo 'image-0.jpg';

Answer 3

Use the php extension Imagick. To control the desired size of the raster output image, use the setResolution function

<?php    
$im = new Imagick();
$im->setResolution(300, 300);     //set the resolution of the resulting jpg
$im->readImage('file.pdf[0]');    //[0] for the first page
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

(Extension on Paolo Bergantino his answer and Luis Melgratti his comment. You need to set the resolution before loading the image.)

Answer 4

Think differently, You can use the following library to convert pdf to image using javascript

Answer 5

You can also get the page count using

$im->getNumberImages();

Then you can can create thumbs of all the pages using a loop, eg.

'file.pdf['.$x.']'

Answer 6

I'm the author of PDFlib which is a GhostScript wrapper for php, advantage of using this library is, it is already tested and it does not require ImageMagic

Always GhostScript commands are faster than ImageMagic when it comes to pdf so you should either go for a GhostScript wrapper or pure GhostScript commands

$pdflib = new ImalH\PDFLib\PDFLib();
$pdflib->setPdfPath($pdf_file_path);
$pdflib->setOutputPath($folder_path_for_images);
$pdflib->convert();
