Working with PDF files in PHP can be a significant challenge. It requires not only the integration of multiple technologies but also the ability to configure the server. To address this, we have developed our own PDF server that handles the most critical operations seamlessly.
Install with Composer
composer require owly-digital/pdf-api-clientYou can retrieve token by contacting us at info@owly.digital
use Owly\PdfApiClient\PdfApiClient;
$client = new PdfApiClient('token');List of available endpoints will change over time. You can also suggest new features by creating issue.
$pdfFiles = [
'path/to/1.pdf',
'path/to/2.pdf',
];
$mergedPdfFile = $client->mergePdfFiles($pdfFiles);
file_put_contents('merged.pdf', $mergedPdfFile);Convert PDF files (also with multiple pages) into various formats.
Parameters:
- Formats:
jpg,png,webp(defaultjpg) - Quality: (detected automatically when omited)
jpg: 0 - 100 (default85)png: 0 - 9 (default9)webp: (default80)
- Resolution (in pixels per inch) (default
600- suitable for printing)
$pdfFiles = [
'path/to/1.pdf',
'path/to/2.pdf',
];
// Basic conversion with automatically detected quality and printable resolution
$convertedFiles = $client->convertPdfFiles($pdfFiles, 'jpg');
// With custom quality and resolution
$convertedFiles = $client->convertPdfFiles($pdfFiles, 'jpg', 50, 300);
// Conversion to webp with custom resolution (default quality)
$convertedFiles = $client->convertPdfFiles($pdfFiles, 'webp', null, 300);
foreach ($convertedFiles as $name => $file) {
file_put_contents('/path/' . $name, base64_decode($file));
}When PDF with multiple pages passed, to each page is added suffix with page number.
Input:
awesomePdfFile.pdf (3 pages)
Output:
awesomePdfFile_0.jpg
awesomePdfFile_1.jpg
awesomePdfFile_2.jpg
$html = "<html><body><h1>Look At Me, I'm PDF now!</h1></body></html>";
// $pdf can be directly forwarded for download
$pdf = $client->convertHtmlToPdf($html);
// or with custom filename
$pdf = $client->convertHtmlToPdf($html, 'awesomePdfFile.pdf');You can customize conversion with DevTools Protocol Options
// Show footer with page numbers
$options = [
'displayHeaderFooter' => true,
'headerTemplate' => '<div></div>',
'footerTemplate' => '<div>Page: <span class="pageNumber"></span> / <span class="totalPages"></span></div>'
];
$pdf = $client->convertHtmlToPdf($html, null, $options);
