The application is composed of a local application and instances running on the Amazon cloud. The application will get as an input a text file containing a list of URLs of PDF files with an operation to perform on them. Then, instances will be launched in AWS (workers). Each worker will download PDF files, perform the requested operation, and display the result of the operation on a webpage. The use-case is as follows:

User gets back an html file containing PDF files after the result of the operation performed on them. Input Files: Each line in the input file will contain an operation followed by a tab ("\t") and a URL of a pdf file. The operation can be one of the following:
- ToImage - convert the first page of the PDF file to a "png" image.
- ToHTML - convert the first page of the PDF file to an HTML file.
