ConvertPdfToTextFromUrlAsynchronously.ps1

      # Cloud API asynchronous "PDF To Text" job example.
# Allows to avoid timeout errors when processing huge or scanned PDF documents.

# If it's not then please replace this with with your hosting url.

# Direct URL of source PDF file.

# Advanced options are properties of TextExtractor class from ByteScout Text Extractor SDK used in the back-end:
