PDF to JPG Converter 作者： Balvin

Convert PDF documents to high-quality JPG/JPEG images
This extension uses online-convert.com's free API to convert PDF documents into high-quality image files. The extension can be used to read PDF documents when there is no PDF reader installed or when the device is not supporting PDF files.

Note that to do the conversions, the extension sends the actual PDF file to the server. Also not that if multiple files are provided, they all get merged into a single file.
