Install & activate (3 minutes)

The plugin works on any WordPress install running PHP 7.4+ and WP 6.0+. No CDN, no external library to set up.

1. Install the plugin

From your WordPress admin, go to Plugins → Add New, search for Tempaloo WebP, click Install then Activate. Or upload the .zip from tempaloo.com/webp via Plugins → Add New → Upload.

2. Generate a license key

Open the new Tempaloo WebP menu in your sidebar. Click Generate a key — a new tab opens on tempaloo.com. Pick the Free plan (250 images/month, no credit card) or any paid plan. You'll be back in WP admin in under 30 seconds with a license key.

3. Activate

Paste the key in the Activate Tempaloo WebP card and click Activate. You're done — every new image upload is now converted automatically.

Bulk-convert your existing library

Open the Bulk tab and click Start conversion. Long jobs survive page refreshes and PHP timeouts thanks to a resumable batch loop.

Under the hood

What the plugin does, in one sentence: it intercepts WordPress's media pipeline (wp_handle_upload + wp_get_attachment_image), sends each new upload to api.tempaloo.com for in-memory conversion, writes the resulting .webp / .avif file alongside the original, and rewrites image URLs so browsers receive the optimized version.

The original files (.jpg, .png, .gif) are never modified. Restoring is one click — see the Restore section.
