Convert a PDF to an image

This package provides an easy-to-work-with class to convert a PDF to one or more image.

Requirements

You should have Imagick and Ghostscript installed. See issues regarding Ghostscript and Imagick Issues for more information.

Installation

The package can be installed via composer and requires PHP 8.2+:

composer require spatie/pdf-to-image

If you are using PHP < 8.2, use version 2.0 of this package.

Usage

Converting a PDF to an image is easy.

$pdf = new \Spatie\PdfToImage\Pdf($pathToPdf);
$pdf->save($pathToWhereImageShouldBeStored);

If the filename you pass to saveImage has the extensions jpg, jpeg, png, or webp the image will be saved in that format; otherwise the output format will be jpg.

The save() method returns an array with the filenames of the saved images if multiple images are saved, otherwise returns a string with the path to the saved image.

Other methods

Get the total number of pages in the pdf:

/** @var int $numberOfPages */
$numberOfPages = $pdf->pageCount();

Check if a file type is a supported output format:

/** @var bool $isSupported */
$isSupported = $pdf->isValidOutputFormat('jpg');

By default, only the first page of the PDF will be rendered. To render another page, call the selectPage() method:

$pdf->selectPage(2)
    ->save($pathToWhereImageShouldBeStored); //saves the second page

Or, select multiple pages with the selectPages() method:

$pdf->selectPages(2, 4, 5)
    ->save($directoryToWhereImageShouldBeStored); //saves the 2nd, 4th and 5th pages

Change the output format:

$pdf->format(\Spatie\PdfToImage\Enums\OutputFormat::Webp)
    ->save($pathToWhereImageShouldBeStored); //the saved image will be in webp format

Set the output quality (the compression quality) from 0 to 100:

$pdf->quality(90) // set an output quality of 90%
    ->save($pathToWhereImageShouldBeStored);

Set the output resolution DPI:

$pdf->resolution(300) // resolution of 300 dpi
    ->save($pathToWhereImageShouldBeStored);

Specify the thumbnail size of the output image:

$pdf
   ->thumbnailSize(400) // set thumbnail width to 400px; height is calculated automatically
   ->save($pathToWhereImageShouldBeStored);

// or:
$pdf
   ->thumbnailSize(400, 300) // set thumbnail width to 400px and the height to 300px
   ->save($pathToWhereImageShouldBeStored);

Set the output image width:

$pdf->size(400) // set the width to 400px; height is calculated automatically
    ->save($pathToWhereImageShouldBeStored);

Set the output image width and height:

$pdf->size(400, 300) // set the width to 400px and the height to 300px
    ->save($pathToWhereImageShouldBeStored);

Get the dimensions of the PDF. This can be used to determine if the PDF is extremely high-resolution.

/** @var \Spatie\PdfToImage\DTOs\PageSize $size */
$size = $pdf->getSize();

$width = $size->width;
$height = $size->height;

Note

$directoryToWhereImagesShouldBeStored must be an existing directory

Save all pages to images:

$pdf->saveAllPages($directoryToWhereImagesShouldBeStored);

Set the Merge Layer Method for Imagick:

$pdf->layerMethod(\Spatie\PdfToImage\Enums\LayerMethod::Merge);

// or disable layer merging:
$pdf->layerMethod(\Spatie\PdfToImage\Enums\LayerMethod::None);

Set the background color of the output image:

$pdf->backgroundColor('white') // simple text for 'white' color
    ->save($pathToWhereImageShouldBeStored);

$pdf->backgroundColor('#fff') // code for 'white' color
    ->save($pathToWhereImageShouldBeStored);

$pdf->backgroundColor('rgb(255,255,255)') // rgb for 'white' color
    ->save($pathToWhereImageShouldBeStored);

Issues regarding Ghostscript

This package uses Ghostscript through Imagick. For this to work Ghostscripts gs command should be accessible from the PHP process. For the PHP CLI process (e.g. Laravel's asynchronous jobs, commands, etc...) this is usually already the case.

However for PHP on FPM (e.g. when running this package "in the browser") you might run into the following problem:

Uncaught ImagickException: FailedToExecuteCommand 'gs'

This can be fixed by adding the following line at the end of your php-fpm.conf file and restarting PHP FPM. If you're unsure where the php-fpm.conf file is located you can check phpinfo(). If you are using Laravel Valet the php-fpm.conf file will be located in the /usr/local/etc/php/YOUR-PHP-VERSION directory.

env[PATH] = /usr/local/bin:/usr/bin:/bin

This will instruct PHP FPM to look for the gs binary in the right places.

Imagick Issues

If you receive an error with the message attempt to perform an operation not allowed by the security policy 'PDF', you may need to add the following line to your policy.xml file. This file is usually located in /etc/ImageMagick-[VERSION]/policy.xml, such as /etc/ImageMagick-7/policy.xml.

<policy domain="coder" rights="read | write" pattern="PDF" />

Testing

spatie/pdf-to-image uses the PEST framework for unit tests. They can be run with the following command:

./vendor/bin/pest
