WorkflowDone – WebP Converter

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 .webp sidecar 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).
