Viewer.js is a JavaScript library for viewing images in the browser with zoom, rotation, flip, move, and keyboard/touch support. It works in modal or inline modes and includes a jQuery plugin wrapper.

Use cases

  • display images in a lightbox with zoom and rotate
  • build an image gallery with fullscreen viewing
  • add touch-friendly image viewing to a mobile web page
  • view a list of images with prev/next navigation
  • embed an inline zoomable image viewer in a web app
  • flip and rotate product photos in a catalog

When to choose

  • you need a lightweight, dependency-free image viewer for the browser
  • you want zoom, rotate, flip, and keyboard/touch support out of the box
  • you need both modal and inline viewing modes

When to avoid

  • you need to view non-image formats like PDFs or videos
  • you need a full image editor with cropping or annotation
  • you are not working in a browser/frontend environment
