GetWebP for WordPress Availability and Getting Started

GetWebP for WordPress is under WordPress.org review. Public installation will be available after approval.

Getting Started with GetWebP for WordPress

GetWebP for WordPress creates generated WebP and optional AVIF copies from Media Library images. Optimization runs in the administrator's browser, and generated files are saved back to your WordPress uploads folder through same-site admin requests.

The free plugin is manual by design: connect a free GetWebP account, preview settings, scan the library, keep the admin tab open during a batch, and review results. The account service manages credits and job metadata; it does not receive image files.

GetWebP uses WebAssembly workers in the administrator's browser. It does not require ImageMagick, GD, Imagick, or another server-side image library for encoding.

Installation#

Public installation will be available after the WordPress.org listing is approved.

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

Availability During WordPress.org Review#

GetWebP for WordPress is under WordPress.org review and is not available for public download yet. The public installation source will be the WordPress.org plugin directory once the listing is approved.

Private ZIP builds are used only for internal testing. Do not install GetWebP from third-party mirrors.

Connect a Free Account#

The current WordPress admin UI requires a GetWebP account connection before scanning the library, previewing quality, or saving optimized files.

  1. Open GetWebP in the WordPress admin sidebar.
  2. Click Connect free account.
  3. Sign in to GetWebP and authorize the site.
  4. Return to WordPress and confirm the dashboard shows account and credit status.

If the browser cannot return automatically to WordPress, use the manual token flow shown by GetWebP.

The account connection is used for site authorization, credit status, and optimization job lifecycle events. Image bytes, decoded pixels, and generated files stay between the administrator's browser and your WordPress site.

Choose Settings#

  1. Open GetWebP in the WordPress admin sidebar.
  2. Choose Balanced, Aggressive, or Ultra.
  3. Enable optional max-width resizing if very large images should be scaled down before generated copies are saved.
  4. Keep WebP enabled. Enable AVIF if you need AVIF files for compatible workflows.
  5. Use Preview quality before a large run.

Supported Inputs and Outputs#

The Media Library scan can include JPEG, PNG, APNG, BMP, HEIC, and HEIF attachments. HEIC and HEIF support depends on the administrator's current browser. Animated GIFs are skipped by the free optimizer.

WebP output is always enabled. AVIF output is optional for compatible workflows, but the standard free frontend delivery path serves generated WebP files.

Run Your First Batch#

  1. Open the GetWebP dashboard and confirm the site is connected.
  2. Scan the Media Library.
  3. Use Preview quality if you want to compare settings before writing files.
  4. Start optimization.
  5. Keep the GetWebP tab open while the browser batch runs.
  6. Stop or continue the run from the same screen if needed.

Free limits:

  • 100 monthly optimization credits
  • 20 images per browser batch

Original images are never modified. Generated WebP and AVIF files are stored as siblings next to the source upload.

Verify Delivery#

The free plugin uses standard WordPress WebP delivery. To verify:

  1. Open a public page with optimized Media Library images.
  2. Open browser DevTools and filter Network requests by images.
  3. Confirm generated .webp URLs are used where WordPress can replace attachment image URLs.

AVIF files may be generated, but the standard free delivery path serves generated WebP files.
