The same concept can be used for forms you may use on your website, but remember, do not have a thumbnail that displays sensitive information. You can easily tell them apart by looking at the cover of the book. For example, textbooks have different versions but keep the same name. This helps visitors locate what they are looking for when the title gets confusing. Thumbnails are images of the PDF that you can view before downloading them.

This makes it the best file format to use when you have forms on your website for which formatting is important, like a W2 form for instance.

This means the file today will look the exact same way on a computer from 2000 and vice versa. The reason the PDF file format has stood the test of time is the fact that it will not compromise what is in the PDF regardless of which hardware you open it on. It is extremely impressive that it is still in use today when you consider how many file formats have become obsolete. What is a PDF?Ī PDF or Portable Document Format is currently the most popular file format in use and was created in 1993 by Adobe. Today I will demonstrate how you can generate PDF thumbnails in WordPress using the GS Only PDF Preview plugin. This was a very common wish before the 4.7 update and many plugins were created to add thumbnails to PDFs. Of course, to keep your website consistent you are going to want all of your PDFs to have thumbnails. This means that all of your older PDFs will not have thumbnails. The problem is this is only for PDFs that you add to your website after the update. Does your website use a lot of PDFs? If so, then you were probably a huge fan of the WordPress 4.7 update that added the automatic PDF thumbnail generation to every PDF added to your website.
