Pan & Zoom Image Using JavaScript And CSS3 Transforms – Panzoom


Panzoom is a lightweight JavaScript library to pan and zoom images inside a container using drag and mouse wheel events.

Not only images, the library also works with Canvas and SVG elements.

How to use it:

Download and import the minified version of the Panzoom library into the html file.

<script src="/path/to/panzoom.min.js"></script>

Insert images to the webpage.

<img class="panzoom" src="1.jpg">
<canvas class="panzoom">
<img class="panzoom" src="1.svg" type="image/svg+xml">

Apply the PanZoom functionality to the images.


Customize the PanZoom functionality with the following options.

PanZoom(".panzoom", {

  // min/max scale
  minScale : 0.1,
  maxScale : 5,

  // increment step
  increment  : 0.05,

  // whether to zoom linearly when using increment
  liner  : false
