What image formats are supported in DITA content?

DITA provides flexibility by supporting multiple image formats for inclusion in documentation. These include all common image formats, scalable vector graphics, PDF, TIFF, and EPS.

  • Common Image Formats: DITA commonly supports popular image formats such as JPEG (Joint Photographic Experts Group), PNG (Portable Network Graphics), GIF (Graphics Interchange Format), and BMP (Bitmap).
  • Scalable Vector Graphics (SVG): DITA fully supports SVG, a vector image format. SVGs are ideal for diagrams, charts, and graphics that need to scale without loss of quality. They are XML-based, allowing for easy editing and localization.
  • PDF (Portable Document Format): While not strictly an image format, DITA allows the inclusion of PDF files. These can contain images, making them suitable for documents with both text and complex graphical elements.
  • TIFF (Tagged Image File Format): TIFF images are supported in DITA, although they are typically used for high-quality print publications due to their lossless compression.
  • EPS (Encapsulated PostScript): EPS images are accepted in DITA and are often used for vector graphics. They can be scaled without loss of quality, making them suitable for print materials.


In a software user manual, an SVG file is used to illustrate a flowchart of a complex process. The SVG format is chosen because it allows for clear scaling and editing. In another section, a PNG image is included to display a screenshot of the software interface. PNG is preferred in this case because it offers lossless compression and maintains the quality of the interface elements.
