WorkflowDone – WebP Converter
·
Converts JPEG and PNG images to WebP on upload, serves them through picture elements, and bulk-converts your existing media library.
WorkflowDone WebP Converter is the simplest plug-and-play WebP solution for WordPress. No configuration required — just activate and go. The plugin automatically detects your server’s capabilities and starts converting images right away.
Most image optimization plugins try to do everything: CDN integration, lazy loading, AVIF, cloud processing, dashboard analytics. This one does exactly one thing — converts your JPEG and PNG images to WebP — and does it reliably with zero setup friction.
Why this plugin?
- True plug-and-play — activate, and it works. No API keys, no cloud accounts, no mandatory configuration. Sensible defaults are already set.
- Universal server compatibility — automatically detects and uses whichever conversion engine your host provides: the PHP GD or Imagick extension. The active backend is shown on the settings page so you always know what’s running under the hood.
- Safe by design — your original files are never touched. The plugin creates .webp sidecar files alongside the originals. If the WebP version would be larger than the source (it happens with some PNGs), the conversion is silently discarded so you never serve a bigger file by accident.
- Lightweight and focused — no bloat, no upsells, no external service dependencies. One small settings page, a handful of options, and a bulk converter. That’s it.
Features
- Convert on upload — generates a
.webpsidecar alongside every uploaded JPEG/PNG, including all registered thumbnail sizes. - Automatic HTML rewriting — wraps
<img>tags in<picture>elements so WebP-capable browsers receive the smaller file while older browsers fall back to the original transparently. - Bulk converter — converts all existing JPEG/PNG images in your media library in batches with a live progress bar and per-result counters (converted / already had WebP / failed).
- Dual-backend detection — automatically selects the GD or Imagick PHP extension, whichever is available on your server. Works on shared hosting, VPS, and dedicated servers alike.
- Smart skipping — skips images that already have an up-to-date WebP sidecar, and skips conversions where the WebP would be larger than the original.
- Configurable quality — choose a quality level between 1 and 100 (default: 80).
