Convert your PDF files to a JPG thumbnail by simply switching the extension of the file to JPG. You can also specify the target thumbnail dimensions using the width and height parameters and any available crop mode. If your PDF file has multiple pages, you can specify the specific page to convert using the page parameter (pg in URLs). For example:

Web applications that manage user data, often allow their users to upload PDF documents. In many cases, you'll want to show a thumbnail of the PDF's cover page for quick identification. You may also want to show thumbnails of the different PDF pages for fast access.

With Cloudinary, you can convert your PDFs (including multi-paged PDFs) to JPGs, PNGs and other image formats.

For example, here's an original PDF file: Original

cloudinary.image("single_page_pdf", { format: 'png' })

You can also generate an image of a specific page from a multi-page PDF.
This can be done by specifying the page parameter (pg in URLs):
