LW Image converts WordPress uploads to WebP (or AVIF) through the HelloImg API — one API call per image, with the original backed up and every reference rewritten. No bloat, no upsell, no tracking.
| Guide | What it covers |
|---|---|
| Usage | How the plugin works day to day: the upload pipeline, bulk optimization, backups and restore, smart crop, and the hooks integrators can use |
| Admin | Every tab of the settings screen and the Media Library integrations |
| WP-CLI | All wp lw-img commands with options and examples |
- Install (
composer require lwplugins/lw-imgor the release ZIP) and activate. - Paste your HelloImg API key on LW Plugins → Image → General. Keys come from app.helloimg.io.
- New uploads convert automatically. For the existing Media Library,
run a bulk optimize from the Bulk tab or
wp lw-img optimize --all.
Requirements: WordPress 6.0+, PHP 8.0+, and an image editor (Imagick or GD) with WebP support — the Tester tab checks all of this for you.
