panzoom is a simple jQuery & Vanilla JavaScript plugin that allows you to drag, pan, zoom in/out any elements of your webpage using CSS3 transforms. Fast, performant and mobile-friendly.

It supports panning and zooming images, text, videos, divs and many other html elements.

Currently works as a Vanilla JavaScript, but can still integrate as a jQuery plugin. You can also download the jQuery Version (3.x) here.

Table Of Contents:

Installation & Download:

# Yarn
$ yarn add @panzoom/panzoom

$ npm install @panzoom/panzoom --save

Basic Usage:

1. Import the panzoom after installation.

import Panzoom from '@panzoom/panzoom'

2. Or directly include the panzoom.js in the document.

<!-- From Local -->
<script src="/path/to/dist/panzoom.min.js"></script>
<!-- From A CDN -->
<script src=""></script>
<!-- Or -->
<script src=""></script>

3. Create an html element you want to apply the panning and zooming functionality on.

<div id="panzoom"> 
  <img src="1.svg" width="900" height="900"> 

5. Create the zoom in/out control buttons (OPTIONAL). To learn how to enable the controls, see the API methods as shown below.

<button id="zoom-in">Zoom In</button>
<button class="zoom-out">Zoom Out</button>
<input type="range" class="zoom-range">
<button class="reset">Reset</button>

6. Attach the plugin to the element and done.

const element = document.getElementById('panzoom')
const panzoom = Panzoom(element, {
      // options here

// enable mouse wheel
const parent = element.parentElement
parent.addEventListener('wheel', panzoom.zoomWithWheel);

7. Full plugin options with default values.

// Whether or not to transition the scale
animate: false,

// This option treats the Panzoom element's parent as a canvas. 
// Effectively, Panzoom binds the down handler to the parent instead of the Panzoom element, so that pointer events anywhere on the "canvas" moves its children. 
canvas: false,

// Default cursor style for the element
cursor: 'move',

// Disable panning and zooming
disablePan: false,
disableZoom: false,

// Pan only on the X or Y axes
disableXAxis: false,
disableYAxis: false,

// Animation duration (ms)
duration: 200,

// CSS easing used for scale transition
easing: 'ease-in-out',

// An array of elements to exclude
exclude: [],

// Or add the CSS class to element that should be excluded
excludeClass: 'panzoom-exclude',

// Override the default handle start event here
handleStartEvent: function (e) {

// min/max scale factors
maxScale: 4,
minScale: 0.125,

// CSS overflow property
overflow: 'hidden',

// Disable panning while the scale is equal to the starting value
panOnlyWhenZoomed: false,

// When passing x and y values to .pan(), treat the values as relative to their current values
relative: false,

// Override the transform setter. 
setTransform: setTransform,

// X Value used to set the beginning transform
startX: 0,

// Y Value used to set the beginning transform
startY: 0,

// Scale used to set the beginning transform
startScale: 1,

// Step options
step: 0.3,

// Contain the panzoom element either inside or outside the parent.
// "inside" | "outside"
contain: null,

// set touch-action on both the Panzoom element and its parent
touchAction: 'none'

8. API methods.

// destroy the instance

// get options

// get the current x/y translation

// get the current scale

// pan the Panzoom element to given x and y coordinates
panzoom.pan(x, y, OPTIONS);

// reset the Panzoom element

// set/update options

// set styles
panzoom.setStyle(name, value);

// zoom the Panzoom element to a given scale
panzoom.zoom(scale, OPTIONS);

// zoom in the Panzoom element

// zoom out the Panzoom element

// zoom the Panzoom element to a focal point using the given pointer/touch/mouse event or constructed point.
panzoom.zoomToPoint(point, pointerEvent, OPTIONS);

// zoom with mouse wheel
// Bind the default down, move, and up event listeners to the Panzoom element. 
// This does not normally need to be called. 
// It gets called by default when creating a new Panzoom object, but can be skipped with the noBind option.

9. Event handlers.

// The event object passed as an argument to the listener will always have a detail property with the current x, y, and scale values.
// Events can be silenced when the silent option is set to true, either globally or when passed to pan, any zoom method, or reset.
// Avoid putting too much logic in these event handlers as it could effect the performance of panning or zooming.

element.addEventListener('panzoomstart', (event) => {
  // do something

element.addEventListener('panzoomchange', (event) => {
  // do something

element.addEventListener('panzoomzoom', (event) => {
  // do something

element.addEventListener('panzoompan', (event) => {
  // do something

element.addEventListener('panzoomend', (event) => {
  // do something

element.addEventListener('panzoomreset', (event) => {
  // do something
