How to Preview A Pdf File In Laravel?

9 minutes read

To preview a PDF file in Laravel, you can use the Embed package to embed the PDF file directly into your view.


First, you'll need to install the package by running composer require vguarneri/laravel-embed.


Next, you can use the embed method in your blade view to display the PDF file. For example, if you have a PDF file stored in your storage directory, you can do something like this:

1

{{ embed(public_path('storage/pdf/myfile.pdf')) }}


This will embed the PDF file directly into your view, allowing users to preview it without needing to download the file.


You can also customize the appearance and behavior of the embedded PDF by passing additional parameters to the embed method. You can find more information on customizing the embedded files in the package documentation.

How to read a PDF file in Laravel?

To read a PDF file in Laravel, you can use a library like "Dompdf" or "TCPDF" which allows you to generate PDF files or read existing PDF files in your Laravel application. Here's how you can read a PDF file using Dompdf:

  1. Install Dompdf library using composer:
1

composer require dompdf/dompdf


  1. Use Dompdf to load and read the existing PDF file in your Laravel controller or wherever you need to read the PDF file:

use Dompdf\Dompdf;

$pdf = new Dompdf();
$pdf->loadHtml(file_get_contents('path_to_your_pdf_file.pdf'));

// Render the PDF file
$pdf->render();

// Get the PDF content
$pdf_content = $pdf->output();

// You can then display the PDF content or store it in a file etc.


Make sure to replace 'path_to_your_pdf_file.pdf' with the actual path to the PDF file you want to read. This code will load the PDF file, render it using Dompdf, and output the PDF content which you can then display or manipulate in your Laravel application as needed.
