Simplify and enhance your work
Great for researchers
Examine, compare, annotate, and share. IIIF enables easy use across repositories, with tools to aid research and presentation.
Efficient for developers
Publish once, reuse often. IIIF serves high-quality digital objects to your own site and others in many formats, without vendor lock-in.
Practical for leaders
Share your collections as widely as possible. IIIF is a cost-effective way to serve billions of digital objects with open-source, community-driven ethics.
The six IIIF APIs fit together to deliver endless possibilities.
Retrieves images from anywhere in the world and allows the user to select an area of the image and to resize, rotate, and edit the quality.
Packages each image with its metadata so users know the origin, title of the image, and even what page of a book the image was from.
Authorization Flow API
Control and restrict access by creating a link to a user interface for logging in and services that provide credentials.
Content Search API
Perform search for text within or annotations related to digital objects.
Change Discovery API
Harvest any changes published by organizations that deliver digital objects.
Content State API
Generate a very specific link to a particular view of an object, like a specific area on a particular page rotated at a certain angle.
