    Default false
  • enableZoomboolean

    Enable zooming functionality. If set to false - scrolling and pinching would not zoom.

    Defaulttrue
  • enforceBoundaryboolean* Experimental

    Restricts zoom so image cannot be smaller than viewport

    Defaulttrue
  • mouseWheelZoombool/string

Methods

  • get()object

    Get the crop points, and the zoom of the image.

  • bind({ url, points, orientation, zoom })Promise

    Bind an image to the croppie. Returns a promise to be resolved when the image has been loaded and the croppie has been initialized.

    Parameters
    • url URL to image
    • points Array of points that translate into [topLeftX, topLeftY, bottomRightX, bottomRightY]
    • zoom Apply zoom after image has been bound
    • orientation Custom orientation, applied after exif orientation (if enabled). Only works with enableOrientation option enabled (see 'Options').
      Valid options are:
      • 1 unchanged
      • 2 flipped horizontally
      • 3 rotated 180 degrees
      • 4 flipped vertically
      • 5 flipped horizontally, then rotated left by 90 degrees
      • 6 rotated clockwise by 90 degrees
      • 7 flipped horizontally, then rotated right by 90 degrees
      • 8 rotated counter-clockwise by 90 degrees
  • destroy()

    Destroy a croppie instance and remove it from the DOM

  • result({ type, size, format, quality, circle })Promise

    Get the resulting crop of the image.

    Parameters
    • type The type of result to return defaults to 'canvas'
    • 'base64' returns a the cropped image encoded in base64
    • 'html' returns html of the image positioned within an div of hidden overflow
    • 'blob' returns a blob of the cropped image
    • 'rawcanvas' returns the canvas element allowing you to manipulate prior to getting the resulted image
    • size The size of the cropped image defaults to 'viewport'
    • 'viewport' the size of the resulting image will be the same width and height as the viewport
    • 'original' the size of the resulting image will be at the original scale of the image
    • {width, height} an object defining the width and height. If only one dimension is specified, the other will be calculated using the viewport aspect ratio.
    • format Indicating the image format.
    • Default:'png'
    • Valid values:'jpeg'|'png'|'webp'
    • quality Number between 0 and 1 indicating image quality.
    • Default:1
    • circle force the result to be cropped into a circle
    • Valid Values:truefalse
  • rotate(degrees)

    Rotate the image by a specified degree amount. Only works with enableOrientation option enabled (see 'Options').

    • degrees Valid Values:90, 180, 270, -90, -180, -270
  • setZoom(value)

    Set the zoom of a Croppie instance. The value passed in is still restricted to the min/max set by Croppie.

    • value a floating point to scale the image within the croppie. Must be between a min and max value set by croppie.

Events

  • update(croppie)Croppie

    Triggered when a drag or zoom occurs

    
$('.my-croppie').on('update.croppie', function(ev, cropData) {});
// or
document.getElementById('another-croppie').addEventListener('update', function(ev) { var cropData = ev.detail; });

Demos

Basic Example 

var basic = $('#demo-basic').croppie({
    viewport: {
        width: 150,
        height: 200
    }
});
basic.croppie('bind', {
    url: 'demo/cat.jpg',
    points: [77,469,280,739]
});
//on button click
basic.croppie('result', 'html').then(function(html) {
    // html is div (overflow hidden)
    // with img positioned inside.
});

Vanilla Example 

var el = document.getElementById('vanilla-demo');
var vanilla = new Croppie(el, {
    viewport: { width: 100, height: 100 },
    boundary: { width: 300, height: 300 },
    showZoomer: false,
    enableOrientation: true
});
vanilla.bind({
    url: 'demo/demo-2.jpg',
    orientation: 4
});
//on button click
vanilla.result('blob').then(function(blob) {
    // do something with cropped blob
});
Resizer Example 

var el = document.getElementById('resizer-demo');
var resize = new Croppie(el, {
    viewport: { width: 100, height: 100 },
    boundary: { width: 300, height: 300 },
    showZoomer: false,
    enableResize: true,
    enableOrientation: true,
    mouseWheelZoom: 'ctrl'
});
resize.bind({
    url: 'demo/demo-2.jpg',
});
//on button click
resize.result('blob').then(function(blob) {
    // do something with cropped blob
});
Upload Example (with exif orientation compatability) 

$uploadCrop = $('#upload-demo').croppie({
    enableExif: true,
    viewport: {
        width: 200,
        height: 200,
        type: 'circle'
    },
    boundary: {
        width: 300,
        height: 300
    }
});

Hidden Example

When binding a croppie element that isn't visible, i.e., in a modal - you'll need to call bind again on your croppie element, to indicate to croppie that the position has changed and it needs to recalculate its points.


$('#hidden-demo').croppie('bind')

Important Notes

Image Hosting & Cross Origin Errors

Croppie uses canvas.drawImage(...) to manipulate images. Thus, images must obey the CORS policy. More info can be found here.

Visibility and Binding

Croppie is dependent on it's container being visible when the bind method is called. This can be an issue when your croppie component is inside a modal that isn't shown. Let's take the bootstrap modal for example..


var myCroppie = $('#my-croppie').croppie(opts);
$('#my-modal').on('shown.bs.modal', function(){ 
    myCroppie.croppie('bind', bindOpts);
});

If you are having issues getting the correct crop result, and your croppie instance is shown inside of a modal, try taking your croppie out of the modal and see if your issues persist. If they don't, then make sure that your bind method is called after the modal is done animating.

Croppie is supported in the following browsers:
