Install and activate the GetWebP WordPress plugin, run your first batch conversion, and start serving WebP and AVIF images in minutes.

Getting Started with GetWebP for WordPress

GetWebP for WordPress converts your media library images to WebP and AVIF directly on your server — no third-party uploads, no cloud dependency. This guide walks you through installation, activation, and your first batch conversion.

GetWebP uses WASM-based encoding and does not require ImageMagick, GD, or any server-side image library.

Installation#

Via WordPress Admin (recommended)

  1. Log in to your WordPress admin panel.
  2. Go to Plugins → Add New.
  3. Search for GetWebP.
  4. Click Install Now, then Activate.

Via WordPress.org

  1. Download the plugin ZIP from wordpress.org/plugins/getwebp.
  2. Go to Plugins → Add New → Upload Plugin.
  3. Upload the ZIP and click Install Now, then Activate.

Via WP-CLI

wp plugin install getwebp --activate

Activate a License Key (optional)#

The free tier works without a license key. If you have a paid plan:

  1. Go to GetWebP → Settings → License.
  2. Paste your license key and click Activate.
  3. Your quota and plan details appear immediately.

You can manage your license keys and view quota usage at getwebp.com/dashboard/licenses.

Run Your First Batch Conversion#

  1. Go to GetWebP in your WordPress admin sidebar.
  2. The dashboard shows how many unoptimized images are in your media library.
  3. Click Start Batch Conversion.
  4. Progress updates in real time — you can leave the page and come back; the background queue continues processing.

After conversion, each image in your media library shows a WebP ✓ (and AVIF ✓ if enabled) status badge.

Original images are never modified. WebP and AVIF files are stored as siblings (e.g., photo.jpg → photo.jpg.webp).

Verify Delivery is Working#

  1. Open any page on your site that contains images.
  2. Open your browser's DevTools → Network tab → filter by Img.
  3. Check the Content-Type header of image responses. You should see image/webp or image/avif for supported browsers.

Alternatively, use WebPageTest or Google PageSpeed Insights to confirm next-gen format delivery.
