Magento 2 Allow PDF file in Wysiwyg Editor.

In this post we’ll guide you how to Allow PDF file on CMS Page, CMS Block and Product page Wysiwyg Editor.

We have add this post just because lot’s of peoples finding a way for add or insert a PDF file in Wysiwyg Editor on Magento 2.

By default Magento does not provide functionality for that. So, you need to create a custom module or use your any exsisting module and create few files on that which are mentioned on below.

Make magento allow pdf files upload on back office. There’s two steps :

  • Add pdf to allowed extensions type. With that modification only, the files would upload but with an exception because magento tries to resize the pdf.
  • Override the upload method to resize images only.

First you need to create di.xml file at app/code/[Company]/[Module]/etc/di.xml and past above code into that file.

<?xml version="1.0"?>
<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Cms\Model\Wysiwyg\Images\Storage">
            <argument name="extensions" xsi:type="array">
                <item name="allowed" xsi:type="array">
                    <item name="pdf" xsi:type="number">1</item>
    <preference for="Magento\Cms\Model\Wysiwyg\Images\Storage" type="[Company]\[Module]\Model\Cms\Wysiwyg\Images\Storage" />

Second you need to create Storage.php file at app/code/[Company]/[Module]/Model/Cms/Wysiwyg/Images/Storage.php and past above code into that file.

namespace [Company]\[Module]\Model\Cms\Wysiwyg\Images;
class Storage extends \Magento\Cms\Model\Wysiwyg\Images\Storage
    public function uploadFile($targetPath$type = null)
        /** @var \Magento\MediaStorage\Model\File\Uploader $uploader */
        $uploader $this->_uploaderFactory->create(['fileId' => 'image']);
        $allowed $this->getAllowedExtensions($type);
        if ($allowed) {
        $result $uploader->save($targetPath);
        if (!$result) {
            throw new \Magento\Framework\Exception\LocalizedException(__('We can\'t upload the file right now.'));
            // Change Start
        if (strtolower($uploader->getFileExtension()) !== 'pdf') {
            // Create Thumbnail
            $this->resizeFile($targetPath '/' $uploader->getUploadedFileName(), true);
        $result['cookie'] = [
            'name' => $this->getSession()->getName(),
            'value' => $this->getSession()->getSessionId(),
            'lifetime' => $this->getSession()->getCookieLifetime(),
            'path' => $this->getSession()->getCookiePath(),
            'domain' => $this->getSession()->getCookieDomain(),
        return $result;
php bin/magento cache:clean

Once you are done with that, it’s pretty straightforward. Add the pdf just like you would do with any image link.

That’s it.
