pdf2preview is a free online tool to generate PDF preview image for academic PDFs. Tough, it works on any kind of PDF, but it is primarily meant for publications. It can generate 3 type of preview images in very high quality PNG format that you can use anywhere. On top of that, it is a completely open source tool too. You can run it locally as well and generate PDF previews on the go.
PDF files don’t have default previews. In order to show you an abstract view of the PDF either in Windows or on webpages, you need to generate a cover image for it. For that, you usually need Illustrator or some other kind of PSD suites. But with pdf2preview, you will not have to do it as it can generate a preview for you in just one click.
For now, you can generate 3 types of PDF image previews and they are; stack, cover, and unroll. In cover mode, it will take the first page of the PDF and will convert it to the preview image. In the stack mode, it will also use the first page for preview but will add stack effect on it. The unroll mode of the tool will generate preview image using all the images in scatter view.
