TinyMCE Native Integration for Serverless File Uploads

Please note this guide is for TinyMCE’s feature and not for our File Uploader.

TinyMCE is a leading WYSIWYG editor that powers 100M sites on the web. TinyMCE provides a native integration to Uploadcare via its Image Optimizer feature.

Every image uploaded via Image Optimizer is instantly cached on our CDN and swiftly and reliably delivered across 130+ countries. This improves front-end performance for your app users, and cuts down development time. With Image Optimizer, developers don’t have to waste time writing code for image configuration and responsiveness. It’s built in!

This guide covers configuring the Image Optimizer widget in the latest version of TinyMCE.

You can see a demo of TinyMCE’s Image Optimizer, as well as advanced configuration instructions, here.

TinyMCE’s integration currently only supports uploading of images. The integration will expand in 2025 to support video and other types of file uploads.

Get a TinyMCE Account

To use Image Optimizer in TinyMCE, you will need a TinyMCE subscription that includes the feature. Contact the TinyMCE sales team to set up an account with Image Optimizer access. Your subscription will include an Uploadcare account*, and access to a separate Uploadcare admin portal.

While it’s currently only available through sales-assisted subscriptions, Image Optimizer will be available to TinyMCE self-service customers in 2025.

* If you already have an Uploadcare account, the TinyMCE sales team can help you connect that account to your TinyMCE account.

Prepare Your TinyMCE Installation

To install a basic TinyMCE setup in your application, update your index.html file with the following code:

10<p>The genus <em>Zostera</em>, or eelgrass, plays a vital role in marine ecosystems, thriving in shallow coastal waters on sandy or muddy substrates. These seagrasses perform underwater photosynthesis, forming the foundation of complex food webs and serving as crucial habitats for marine life. <em>Zostera</em> beds offer nursery grounds for juvenile fish and invertebrates, bolstering biodiversity. Additionally, their extensive root systems stabilize shorelines by trapping sediment, mitigating erosion, and sequestering carbon more efficiently than terrestrial forests, contributing to climate change mitigation.</p>
11<p>Beyond their structural and ecological contributions, <em>Zostera</em> supports symbiotic relationships with various organisms. Epiphytic algae and microorganisms colonize its leaves, while small invertebrates feed on these epiphytes and find shelter among the seagrass blades. These interactions create a balanced and thriving habitat.</p>

Configure Image Optimizer

Now let’s configure Uploadcare for TinyMCE. The code below is required to activate the Image Optimizer plugin:

1tinymce.init({
2  selector: 'textarea',
3  plugins: 'uploadcare',
4  toolbar: 'uploadcare',
5  uploadcare_public_key: 'YOUR-PUBLIC-KEY'
6});

Make sure to replace YOUR_PUBLIC_KEY in the above snippet with your Uploadcare Public API Key.

Your complete TinyMCE code snippet should now read:

1<!DOCTYPE html>

Save your page and open it in your browser. Now you can save images directly from TinyMCE into your Uploadcare account!

The Image Optimizer feature works with Uploadcare to automatically compress images and generate responsive versions suitable for any display and needed resolution. Once it’s integrated with TinyMCE, it will look like this:

Сompressed image

Conclusion

Good job, you’ve just enabled serverless image uploading and optimization in your TinyMCE editor 🙂

Now your users can quickly drag and drop images from their local files or import from a URL, and immediately adjust the pictures to fit their needs. With Image Optimizer, over a dozen image enhancement tools are already available to users, along with their image which is cached in our CDN upon upload. No need to write code for responsiveness or compression. It’s that easy!
