Dezoomify extracts full high-resolution images from online zoomable image interfaces.It works with several zoomable image tools, from several different websites (see the list below).It takes as input the URL of a a zoomable image and gives as output an image that you can download (by right-clicking on it, and choosingSave Image as...).

In order to find the URL of the zoomable that dezoomify requires, you can install thedezoomify browser extension. Alternatively, you can also try tofind the zoomable image URL yourself.

If you are not interested in the source code and just want to assemble tiles of (dezoomify) a zoomify-powered image, go there :unzoomify an image

If you have problems while downloading an image, then read theFAQ.

Your bug reports and feature requests are welcome!Please go the theGithub issue page of the project,and explain your problem.Please be clear, and give the URL of the page containing the image dezoomifyfailed to process.

The aim of the script is to do as much as possible inJavascript (with the HTML5<canvas> tag), and only the network-related stuffs on the server side. The only little piece of server-side code that remains in the code is just a proxy, used to circumvent thesame-origin policy.We implemented this code both in Javascript (node-app/proxy.js) and PHP (proxy.php), so you just need to have either oneon your server to run dezoomify.

This script on wikimedia :Zoomify in the help about zoomable Images on wikimedia

You can run the script locally, using php:

# Install the dependenciessudo apt install php-cli# Run the scriptphp -S localhost:3000

Then openhttp://localhost:3000/ in your browser.
