IIIF server

What is a IIIF server?

IIIF stands for “ International Image Interoperability Framework ”. A IIIF server is a special type of server that serves images according to IIIF standards. These standards were developed to facilitate the sharing, presentation and in-depth analysis of high-resolution images over the Internet. IIIF is widely used by libraries, Archive , museums, and other institutions to make digital collections more accessible and interactive.

Core functions of a IIIF server:

  • Image delivery in different resolutions: A IIIF server can deliver images in the required size, crop and resolution without having to store multiple versions of the image. Users can zoom in on a portion of an image to see details without having to load the entire image in high resolution.
  • Interoperability: Images served by a IIIF server can be used in a variety of IIIF-compatible applications and tools. This allows users to view, compare and analyze digital images from different sources in a unified manner.
  • Metadata enrichment: IIIF also supports delivering metadata along with the images. This metadata may Info about the image itself, its content, copyright and other relevant data.
  • Annotation support: IIIF allows you to add annotations to images. These can range from simple comments to complex scientific annotations.

Application examples:

  • Digital libraries and Archive : Institutions can provide high-resolution scans of books, manuscripts, and other documents through a IIIF server so that researchers and the public can view them in detail.
  • Museums and art galleries: Artworks can be digitized and placed online, with users able to search every detail of the search .
  • Education: Teaching materials and historical documents can be made accessible for teaching and research, giving students the opportunity to explore materials in an interactive way.


A IIIF server therefore offers a powerful and flexible solution for the online presentation and analysis of digital images and promotes the accessibility and scientific and educational use of digital collections.
