Palleon - Javascript Image Editor

Please note that, if you open index.html file directly on your browser, it may not work properly. Most browsers restricts the kinds of files that pages can load (and methods of loading) when you open them from a file:// URL. You should upload the folder to your hosting or create local server environment on your computer using a third party app. For example; MAMP.



This folder contains images.


This folder contains all CSS files. There are two ready themes (light and dark) you can use.


This folder contains all elements, frames, icons and templates hierarchically.


This folder contains all javascript files. All javascript plugins (except FabricJS) we've used are in js/plugins.min.js file.


This folder contains 2 json file which are required for loading "Google Fonts" and "Material Icons".

To open a new image on the photo editor, click New button. A modal box will appear;

Click this upload image button to select an image from your computer.

Click select from media library button to select an image from WordPress media library.

If you have a template (.json file) which you’ve created with Palleon before, use upload template button to open it on the photo editor.

If you want to open a default image on the first page load find the following line on index.html file;

<img id="palleon-canvas-img" src="" data-filename="" />

and add your file url and name like the following;

<img id="palleon-canvas-img" src="assets/placeholder-big.jpg" data-filename="placeholder" />

All: All frames are on this tab.

My favorites: Click the star icon on any frame, and you will see it here next time you visit.

Palleon comes with hundreds of multipurpose icons ready to use. You can also upload your custom SVG files to the canvas. Please keep in mind that SVG files are made by different designers using different softwares. So, some custom SVG files may not displayed properly on the canvas.

Canvas Ruler

If you are working on a blank canvas, you can change the background color from this section. This section also contains user preferences.

Palleon is built on JQuery and FabricJS. So, starting from FabricJs Docs may be a good idea to learn how FabricJs works.


We recommend you not to edit original js/palleon.js file if it is not necessary. You can add your custom javascript functions to js/custom.js file. We added some example functions for you. You can find all you need to integrate Palleon with your app on this file.

baseURL: You may need to add the url of the main directory when you upload it to your site. For example;

baseURL: "",

How to add my own templates?

1) Create something with the image editor and download as template (You can also upload this JSON file directly to the editor from New->Upload Template).

2) Put the JSON file into Files->Templates->Json folder.

3) Create a thumbnail image and put the image into Files->Templates->img folder.

4) Open index.html file and add your template into #palleon-templates-grid div like the following example;

<div id="palleon-templates-grid" class="palleon-grid template-grid template-selection paginated" data-perpage="21">
<div class="grid-item" data-keyword="MY TEMPLATE" data-category="blog-banners">
<div class="template-favorite">
<button type="button" class="palleon-btn-simple star"><span class="material-icons">star_border</span></button>
<div class="palleon-masonry-item-inner palleon-select-template" data-json="YOUR_JSON_URL">
<div class="palleon-img-wrap">
<div class="palleon-img-loader"></div>
<img class="lazy" data-src="YOUR_THUMBNAIL_URL" title="MY TEMPLATE" />
<div class="palleon-masonry-item-desc">MY TEMPLATE</div>

The following data attributes are important;

data-perpage: The number of templates on the page. Required for pagination plugin.

data-keyword: The keyword which is used on template search.

data-category: The category which is associated with the template.

data-json: The url of the JSON (template) file.

data-src: The url of the thumbnail image. We used lazyload so there is no need to add src attribute.
