Check out the demo and feel free to load your own manifests by changing the URL.

Embedding TIFY

TIFY is available as an npm package:

npm install tify

To embed TIFY into your site:

  1. Copy the contents of the dist/ directory to your server.
  2. Add an HTML element serving as the container.
  3. Include tify.js.

The container element should have the following CSS applied:

  • either position: relative or position: absolute
  • height and width

The required HTML code looks something like this:

<div id="tify"></div>
<script src="tify.js"></script>

The only required parameter manifest is a URL pointing to the manifest. It can be set either as a query parameter or with the tifyOptions object, whereby the latter takes precedence.


  • container (string or HTMLElement, default #tify): The HTML element TIFY is loaded into.
  • immediateRender (boolean, default true): Set this to false to render lower resolution tiles until the full resolution is loaded, providing the effect of blurry to sharp. Note that this increases loading times.
  • init (boolean, default true): TIFY is initialized immediately when the script is loaded. Set this to false if you prefer to initialize TIFY only by calling window.Tify.init().
  • language (string, default en): The interface language. Currently, only English and German (de) are available.
  • manifest (string): A URL pointing to the IIIF manifest. If this option is not set, the URL has to be provided via a query parameter of the same name.
  • stylesheet (string): Use this to provide your own stylesheet, replacing TIFY's default styles. Set to null to prevent TIFY from loading any styles, e.g. if your site's stylesheet already includes styles for TIFY.
  • title (string, default: TIFY): By default, TIFY replaces the window title with the document title as defined by the manifest, appended by TIFY. Set this to any string, or null to disable title modification.


Below an example with all available options set.

<div id="viewer"></div>
	tifyOptions = {
		container: '#viewer',
		immediateRender: false,
		init: true,
		language: 'de',
		manifest: 'https://example.com/iiif/manifest.json',
		stylesheet: '../styles/my-very-own-tify-styles.css',
		title: null,
<script src="tify.js"></script>

Build Setup

Install dependencies:

npm install

Run in development mode with hot reload on localhost:8080:

npm run dev

In development mode, the manifest URL must be provided via query parameter, e.g. http://localhost:8080/?manifest=https://manifests.sub.uni-goettingen.de/iiif/presentation/PPN857449303/manifest.

Build for production with minification:

npm run build

The production build will be stored in dist, just copy the contents of this directory to your server.
