Everything you expect from an image cropper

Doka packs everything you could need when cropping images, because of its beautiful device agnostic design it fits in everywhere.

Enforce Aspect Ratio

Enforce a specific crop aspect ratio to make sure output images always fit perfectly. Offer creative freedom by defining a range of aspect ratios to choose from.
Client-side Transforms

Boost file upload speed and lower server bandwidth usage by compressing, resizing, and converting the files on the client. Doka can output both raster and vector data.
Rotate, Resize and Flip

Rotate, resize and flip pictures to make the perfect selection. Resize with the mouse wheel or mobile multi-touch controls.

Quickly turn images in 90° steps, finetune the result using the rotation control at the bottom of the viewport.
Responsive and Accessible

Automatically scales to available space. Can be controlled by Touch, Mouse, and/or Keyboard.

Doka is functional on both mobile and desktop browsers and has been successfully tested on fast and slow devices.

A user-friendly approach to image cropping

Empower your users to personalize their profile pages.

On big viewports we can use preview mode to help the user edit an image in place. This makes it possible to judge the result before confirming the crop.

Editing the profile picture in place would be cumbersome. By switching Doka to full view mode we can create more room for the editing experience.

Hit the ground running with FilePond

Use Doka and FilePond together to create a streamlined editing and uploading experience.

JavaScript

// We create a Doka editor instance. Now we can use this instance
// to load file objects, it will automatically open them fullscreen
const doka = Doka.create({
  cropAspectRatioOptions: [
    { label: 'Free', value: null },
    { label: 'Portrait', value: 1.25 },
    { label: 'Landscape', value: .75 }
  ]
});

// Listen for changes on a file input element
const input = document.querySelector('input[type="file"]');
input.addEventListener('change', e => {

  // Edit the loaded file with Doka
  doka.edit(input.files[0])
    .then(({ file }) => {
      // "file" is the transformed file object
    });

});

// With FilePond we do the actual file transformation outside
// of Doka, as that allows for faster image previews
FilePond.registerPlugin(
  FilePondPluginImageExifOrientation,
  FilePondPluginImagePreview,
  FilePondPluginImageEdit,
  FilePondPluginImageCrop,
  FilePondPluginImageResize,
  FilePondPluginImageTransform

Dropzone.options.dokaDropzone = {

  // Link up Dropzone with Doka using our custom "transformFile" function
  transformFile: useDokaWithDropzone({
    cropAspectRatioOptions: [
      { label: 'Free', value: null },
      { label: 'Portrait', value: 1.25 },
      { label: 'Landscape', value: .75 }
    ]

    cropAspectRatioOptions: [
      { label: 'Free', value: null },
      { label: 'Portrait', value: 1.25 },
      { label: 'Landscape', value: .75 }
    ]
  }),

  // Set other Uppy properties here
  id: 'uppy'

});

jQuery File Upload

    { label: 'Free', value: null },
    { label: 'Portrait', value: 1.25 },
    { label: 'Landscape', value: .75 }
  ]

$('#fileupload').fileupload({
