The tools are:

• Explore PDF
  This function provides an insight into the internal structure of a file, offering a variety of views that reveal features like the content stream or resources like fonts, ICC profiles and more. Among other applications, the tool is useful for hunting down invalid PDF files.

• Explore Fonts
  Complementing “Explore PDF”, this tool lets users analyze embedded fonts, including their internal encoding or glyphs.
  
• Explore Metadata
  This tool can be used to output or export both the metadata within a PDF document and the metadata related to any images the document contains.
  
• Explore Layers
  The layer explorer shows a list of all layers within the document, as well as their visibility setting. It also supports metadata in line with the ISO standard on processing steps.
  
• Explore Tagging
  This tool visualizes a file’s internal tagging structure and elements like headings, paragraphs or image captions.

• Explore DPart
  This viewer identifies all DPart information that applies to pages or page regions, making it easier to set up automatic DPart-based processes.

• Extract Barcode
  By analyzing barcodes and QR codes, this tool delivers both the encoded data and any parameters that are relevant for printing, such as bar width reduction and module width.
  
• Test Mode
  This tool lets users test, improve and export any pdfToolbox profile using any test file. However, if the user does not have a license, the output PDF file will no longer be available once Test Mode is closed.
