Generates a thumbnail which can be used however you need to. Great for building a library of pdfs – wrap the shortcode in a link and BANG, you’re done! ![](https://secure.gravatar.com/avatar/5e5750dffa01a908cef8e9630bb6febf08e8e533796793a3c74e11743fd19edf? s=60&d=retro&r=g) ### 󠀁[Invaluable for building document libraries and the like](https://wordpress.org/support/topic/invaluable-for-building-document-libraries-and-the-like/)󠁿 [Jeremy Varnham](https://profiles.wordpress.org/jvarn13/) 2024년 8월 1일 I’ve used this on multiple sites and have found it invaluable. While I’ve struggled with getting the required ImageMagick set up and working on a few servers – each one requiring a slightly different approach owing to different OS and security settings– this is not the fault of the plugin or plugin author. I’m not sure what one reviewer means by this being built-in to WordPress; to the best of my knowledge that is incorrect. ![](https://secure.gravatar.com/avatar/303518c80f6f6085242214a06a4fadfee403716e4606b4e220c8af7fdb0fd594? s=60&d=retro&r=g) ### 󠀁[Very Helpful, Simple Yet Customizable](https://wordpress.org/support/topic/very-helpful-simple-yet-customizable/)󠁿 [hommealone](https://profiles.wordpress.org/hommealone/) 2024년 7월 19일 In certain situations, this can be a very handy plugin. It works as advertised. It is simple to use, and allows developers many options of how to implement it and customize it when needed. Using custom fields for file uploads, I’ve built this into template files, so my customers can simply upload their PDF files and have them presented nicely with no further effort required. In the right situation, it can save many tedious and repetitive steps. It allows my clients to easily and automatically present their PDF files in an attractive way without having to fire up Photoshop or some other image creation method each time. No more need to upload a PDF file and a separate image file. This plugin takes care of it all in one easy step. p. s. – the developer seems to be excellent at responding to questions in the plugin’s forum page too! ![](https://secure.gravatar.com/avatar/2225189e8044df879b3326c1371fcd0b2ce35b545f212ee06d580bab8c273539? s=60&d=retro&r=g) ### 󠀁[High level of customization](https://wordpress.org/support/topic/high-level-of-customization/)󠁿 [cvladan](https://profiles.wordpress.org/cvladan/) 2022년 12월 28일 This plugin exceeded my expectations by allowing me to dynamically preview a PDF file without any links to it or similar. One of the standout features of this plugin is its high level of extensibility. With numerous hooks provided, it is easy to customize and tailor the plugin to meet specific needs and requirements. ![](https://secure.gravatar.com/avatar/89b43d8d32b1049c31184d69670160c3bb02d1f74506aaf427b2f921278eb5a1? s=60&d=retro&r=g) ### 󠀁[Very Useful Plugin](https://wordpress.org/support/topic/very-useful-plugin-1374/)󠁿 [hilmon](https://profiles.wordpress.org/hilmon/) 2022년 10월 10일 Plugin works great.
