Web Standard: Formats


Programs create different kinds of files which are published to various formats.  They have different file extensions (e.g.; .pdf, .doc, .pptx).

Content Requirements

  • The EPA standard formats for publishing information on the Web are HTML and PDF.
  • Proprietary formats (.wpd, .doc, .xls, .ppt) should be used only when absolutely necessary (e.g., when providing forms for customers to complete and submit or for spreadsheets that they will use).
  • Proprietary formats are more likely to become redundant, outdated or trivial.  They are hardly ever updated.
