The [`rmagick`](https://rmagick.github.io/) gem is a wrapper around the

|
|
|
```ruby
|
|
require 'rmagick'
|
|
pdf = Magick::ImageList.new('document.pdf')
|
|
first_page = pdf.first
|
|
scaled_page = first_page.scale(300, 450)
|
|
scaled_page.write('document-thumbnail.jpg')
|
|
```
|
|
|
|
The scale can be adjust as necessary to the use case.
