This tutorial presents the following topics. Click a timestamp to jump to that part of the video.### Introduction to PDF generation
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=00 :player=cld} | PDFs are a popular format for business documents and widely accepted file types. Cloudinary makes it easy to generate PDFs from images in your product environment. |

### Tagging images for PDF generation
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=16 :player=cld} | Learn how to tag images in your product environment so they can be grouped together for PDF generation. Tags serve as metadata that allows you to retrieve specific image collections programmatically. |

### Creating PDFs with the Node.js SDK
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=47 :player=cld} | Set up a Node.js script to generate PDFs from tagged images using the `cloudinary.uploader.multi()` [Admin API method](image_upload_api_reference#multi). Configure transformations including width, crop mode, and gravity settings for optimal PDF layout. |

### Configuring PDF transformations
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=18 :player=cld} | Apply transformations to ensure images fit properly in the PDF format, including setting width to 800px, using fill crop mode, and automatic gravity for optimal image positioning. |

### Security settings for PDF delivery
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=2 :sec=08 :player=cld} | By default, PDF and ZIP files are blocked for security. To enable PDF delivery, navigate to the [Security](https://console.cloudinary.com/app/settings/security) page of the Console Settings and check **Allow delivery of PDF and ZIP files**. |

### Dynamic PDF generation with uploads
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=2 :sec=36 :player=cld} | Create a dynamic workflow that uploads multiple images with tags and immediately generates a PDF. Perfect for applications where users upload images that need to be compiled into documents. |

### Uploading and tagging images programmatically
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=3 :sec=33 :player=cld} | Use a loop to upload multiple images with consistent tags, then generate a PDF from the newly uploaded and tagged images using the same multi-image PDF generation technique. |

```node.js
const images = [
    "./images/sample.jpg",
    "./images/sample-2.jpg"
];

for (const image of images){
    await cloudinary.uploader.upload(image,{
        tags: "vacation"
    });
}
```
