# Convert a PDF to an image
[](https://packagist.org/packages/spatie/pdf-to-image)
[](LICENSE.md)
[](https://scrutinizer-ci.com/g/spatie/pdf-to-image)
[](https://packagist.org/packages/spatie/pdf-to-image)
This package provides an easy-to-work-with class to convert a PDF to one or more image.
## Requirements
You should have [Imagick](http://php.net/manual/en/imagick.setresolution.php) and [Ghostscript](http://www.ghostscript.com/) installed.
See [issues regarding Ghostscript](#issues-regarding-ghostscript) and [Imagick Issues](#imagick-issues) for more information.
## Installation
The package can be installed via composer and requires PHP 8.2+:
```bash
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.
```php
$pdf = new \Spatie\PdfToImage\Pdf($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:
```php
/** @var int $numberOfPages */
$numberOfPages = $pdf->pageCount();
```
Check if a file type is a supported output format:
```php
/** @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:
```php
$pdf->selectPage(2)
->save($pathToWhereImageShouldBeStored); //saves the second page
```
Or, select multiple pages with the `selectPages()` method:
```php
$pdf->selectPages(2, 4, 5)
->save($directoryToWhereImageShouldBeStored); //saves the 2nd, 4th and 5th pages
```
Change the output format:
```php
$pdf->format(\Spatie\PdfToImage\Enums\OutputFormat::Webp)
->save($pathToWhereImageShouldBeStored); //the saved image will be in webp format
```
Set the output quality _(the compression quality)_ from 0 to 100:
```php
$pdf->quality(90) // set an output quality of 90%
->save($pathToWhereImageShouldBeStored);
```
Set the output resolution DPI:
```php
$pdf->resolution(300) // resolution of 300 dpi
->save($pathToWhereImageShouldBeStored);
```
Specify the thumbnail size of the output image:
```php
$pdf
->thumbnailSize(400) // set thumbnail width to 400px; height is calculated automatically
->save($pathToWhereImageShouldBeStored);
// or:
$pdf
->thumbnailSize(400, 300) // set thumbnail width to 400px and the height to 300px
->save($pathToWhereImageShouldBeStored);
```
Set the output image width:
```php
$pdf->size(400) // set the width to 400px; height is calculated automatically
->save($pathToWhereImageShouldBeStored);
```
Set the output image width and height:
```php
$pdf->size(400, 300) // set the width to 400px and the height to 300px
->save($pathToWhereImageShouldBeStored);
```
Get the dimensions of the PDF. This can be used to determine if the PDF is extremely high-resolution.
```php
/** @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:
```php
$pdf->saveAllPages($directoryToWhereImagesShouldBeStored);
```
Set the Merge Layer Method for Imagick:
```php
$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:
```php
$pdf->backgroundColor('white') // simple text for 'white' color
->save($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`.
```xml
```
## Testing
`spatie/pdf-to-image` uses the PEST framework for unit tests. They can be run with the following command:
``` bash
./vendor/bin/pest
```
