Make a IIIF manifest from images on your computer
On the new “Create a manifest” page, choose images (or a folder) and enter the URL where you will put them, and download a IIIF manifest that points at the images there. Plain image files and IIIF Image API servers are both supported. You can reorder and rename pages, set rights and right-to-left page turning, and check the result in the viewer beside the form. The images stay in your browser and are never sent to a server.
