Top 3 PDF Thumbnail Generators: Easy Solutions for Beginners and Experts

Have you ever wondered how to generate a PDF thumbnail? The right PDF thumbnail generator makes displaying attractive PDF previews in portfolios and other online projects simple. Today we'll explore the best options, from beginner-friendly software like UPDF to more advanced tools for developers. Hang around to the end and you'll find the perfect solution for your needs.

Part 1: Top 3 Thumbnail Generators

If you're looking for a PDF thumbnail generator to help you create attractive representations of your PDFs for use on a website, in emails, or for other purposes, you're in good hands. We'll talk through three ways to create a PDF preview image and take you through the basics for each one.

1. Best PDF thumbnail generator: UPDF

The best way to do anything is usually to use what you already have, and learning how to generate a PDF thumbnail is no different.

If you're already a UPDF user, then you'll be familiar with the huge range of tools included to help you create and manage PDFs. What you might not know, is that it can also generate thumbnails.

There's a download button below so you can pick up UPDF now and follow along as we show you how to change a PDF into a thumbnail, step-by-step.

How to show and hide PDF thumbnails in UPDF

First up, here's a quick tip you might not know about PDF thumbnails. UPDF automatically generates thumbnails for each page of a PDF as soon as you open it.

Just tap the thumbnail button on the left-hand side to display or hide the thumbnail panel.

How do I display a PDF as a thumbnail?

The above method is suitable when you simply need to get PDF pages to show thumbnails in UPDF. If you want to use the thumbnail elsewhere, you'll need the following steps.

This method is helpful if you need a thumbnail or icon to represent a PDF on a website, perhaps as part of a resource library.

Step 1. With the file open in UPDF, identify the page you'd like to turn into a thumbnail.

Step 2. Go to Export PDF > Image on the right-hand menu.

Step 3. Choose an image format from the list. The best file type will depend on how you plan to use the thumbnail, so it's best to check that first.

  • BMP
  • JPEG
  • PNG
  • TIFF
  • GIF

Step 4. Now choose the page you want to use for the thumbnail, and click Export. In the illustration below we're using page 1.

Step 5. Follow UPDF's prompt to choose a folder and save the thumbnail.

There you go. Five easy steps to create a thumbnail image for your PDF. You can take the saved thumbnail and use it anywhere it's needed. So why wait? Try it now!

2. PDF Thumbnail Generator WordPress plugin

For those of you with WordPress websites, the PDF Thumbnail Generator WordPress plugin is a good solution.

Once you've installed the plugin it automatically creates a thumbnail every time you upload a PDF, removing a manual step from your to-do list. This is great for people with a large PDF library that requires thumbnails.

Note

This plugin works with PHP 5.6 or above, and requires the Imagick PHP extension.

Step 1. Install the plugin by going to Plugins > Add New and searching for "PDF Thumbnail Generator."

Step 2. Go to Plugins > Installed Plugins > PDF Thumbnail Generator and select Activate.

Step 3. Allow the plugin to check for server compatibility. This is an automated process.

Step 4. Go to Settings > PDF Thumbnail Generator to adjust the size and quality parameters for the thumbnails.

Step 5. Generating thumbnails:

  • For newly uploaded PDFs, the plugin will automatically generate a thumbnail based on the file's first page.
  • For existing files, locate the PDF in the media library and choose Regenerate Preview.

If you need to generate a lot of PDF thumbnails for a WordPress site, the plugin route might be perfect for you, as long as your site fits the requirements.

If it's something you only need to do occasionally, or if your site doesn't match the requirements, you're better off using one of the other methods.

3. Scandel PDF Thumbnails tool

If you're not afraid to dive into a bit of coding, this next method might work for you. Remember though, if this method is beyond your comfort zone, the UPDF method outlined above is very simple and doesn't require any tech knowledge.

The Scandel PDF Thumbnails tool is a JavaScript-based script that creates thumbnails based on the first page of a PDF. It's perfect for developers and webmasters who need to preview PDF files visually, perhaps for online portfolios or file managers.

  • Getting set up: Download the required code from GitHub. Get the pdf.js PDF viewer from Mozilla.
  • Add the code to your website.
  • Customize the code to change thumbnail size, if needed.

This is a very basic overview of the process, you'll want to review the tool's GitHub page for more details and to ensure you have the relevant knowledge to install and run the tool safely.

Since this is a lightweight, highly customizable option, it's great for people with the required tech knowledge. Any kind of coding has the potential to mess up your website though, so should be approached with caution.

Part 2: Bonus - Why Should You Choose UPDF PDF Thumbnail Generator?

The three techniques for generating thumbnails we outlined above require varying levels of skill to use them.

The Scandel PDF Thumbnails tool is definitely on the higher end when it comes to technical ability. The PDF Thumbnail Generator WordPress plugin is easy enough to use, but it only works for the limited use case of WordPress sites meeting certain specifications.

For the average user, then, the first method is the best.

UPDF offers a fast, simple PDF thumbnail generator that requires almost no technical ability. If you know how to open and save a file, you'll find this easy.

You might also have come across PDF thumbnail generator online tools designed just for that one function. These are great if you're not worried about uploading your document to a third-party website. If you prefer to keep things on your own system, UPDF is your best option.

As well as being an easy way to make PDF thumbnails, UPDF has a range of other tools to help you with general PDF creation, reading, and editing. It's so much easier to download a single tool and learn to use it effectively, rather than seek single-task solutions repeatedly.

UPDF's main benefits to users
