This is a plugin for Imperavi Redactor providing it to work with Uploadcare Widget.

GitHub release  Uploadcare stack on StackShare


Check out the basic demo for:


Imperavi Redactor 2 or 3.


Download the latest plugin archive from the release branch or releases page.

Extract the downloaded archive to the plugin directory of your Redactor installation.

Then, place the plugin in your page after embedding redactor.js:

<!-- redactor js -->

<!-- plugin js -->
<script src="/your-folder/plugins/uploadcare.redactor.min.js"></script>


Add uploadcare to the list of your Redactor plugins. Set your public key. Public keys are used to identify a target Uploadcare project your uploads will go to.

Redactor 3

$R('#editor', {
  plugins: ['uploadcare'],
  uploadcare: {
    buttonIconEnabled: true,
    publicKey: 'YOUR_PUBLIC_KEY',

  plugins: ['uploadcare'],
  uploadcare: {
    buttonIconEnabled: true,
    publicKey: 'YOUR_PUBLIC_KEY',


Plugin configuration

To apply a custom configuration, initialize the plugin providing additional options:

UPLOADCARE_LOCALE = 'ru' /* set locale if you wish */

$R('#editor', {
  plugins: ['uploadcare'],
  callbacks: {
    uploadcareShow: function() { console.log.apply(undefined, arguments) },
    uploadcareDone: function() { console.log.apply(undefined, arguments) },
    uploadcareCancel: function() { console.log.apply(undefined, arguments) },
  uploadcare: {
    /* set your public API key here */
    publicKey: 'demopublickey',
    /* set crop options when handling images */
    crop: 'free,1:1',
    /* show icon instead of "Uploadcare" */
    buttonIconEnabled: true,
    /* feel free to add more “object key” options here */
