About this plugin

Free image optimizer for WordPress — convert your media library to AVIF and WebP and undo it any time. No subscription. Compress your JPEG and PNG images into next-gen AVIF and WebP formats and cut page weight without a recurring fee or monthly image limits. Local conversion is unlimited and free; optional Cloud API credits are only used when your host can’t encode AVIF locally.

WordPress’s built-in conversion runs when an image is uploaded, so images already in your library stay JPEG and PNG unless you reprocess them with a separate tool. Picqlo Image Converter bulk-converts your existing media library for faster page loads and better Core Web Vitals scores, and can also convert new uploads as you add them (turn on Auto-convert on upload in Settings). AVIF and WebP are added alongside your originals rather than replacing them, so your content and image URLs don’t change and you can revert one image or all of them at any time.

Key features:

  • Bulk conversion — convert your entire media library in one click
  • Non-destructive by default — AVIF and WebP conversion never modifies your originals; companion files are placed alongside them and deleted on revert. Lossless Optimize is the exception — it rewrites originals in place but creates a .lossless-bak backup first; reverting restores from the backup
  • AVIF + WebP — AVIF where your server supports it, WebP as a reliable fallback
  • Auto mode — uses AVIF if available locally, WebP otherwise; no manual configuration needed
  • Real-time progress log — live streaming log with encoder badges ([GD], [Imagick], [exec], [API]) and a progress bar
  • Per-image controls — convert, reconvert, revert, or force-cloud on individual images from the Images tab
  • Diagnostics tab — see which encoders are available on your server before you start
  • Cloud API — guaranteed AVIF encoding on any host via the Picqlo Cloud API, even on shared hosting without local AVIF support (requires credits from picqlo.com)

Encoders used (in priority order):

AVIF:
1. GD library (imageavif)
2. ImageMagick (via the Imagick PHP extension)
3. cavif-rs or avifenc binary (via exec, if pre-installed on your server)
4. Picqlo Cloud API — remote AVIF encoder, works on any host (requires API key at picqlo.com)
5. WebP fallback — if AVIF fails on all local encoders, falls back to WebP automatically

WebP:
1. ImageMagick (better quality, ICC profile preserved)
2. cwebp binary (via exec, if pre-installed on your server)
3. GD library (imagewebp)

Cloud API:

The Cloud API is an optional external service for guaranteed AVIF encoding on hosts where no local AVIF encoder is available (e.g. old shared hosting). It requires an API key from picqlo.com. Credits are consumed only when the cloud encoder is actually used; if your server handles AVIF locally, no credits are spent and no data is sent externally.

Privacy: All local processing is entirely local — no data leaves your server. Cloud API processing is in-memory only; images are deleted immediately after conversion. See picqlo.com/privacy.

External Services

This plugin optionally connects to the Picqlo Cloud API (api.picqlo.com), a remote AVIF encoding service. The Cloud API is only used when:

  1. An API key has been entered in the plugin settings, AND
  2. A conversion is initiated that uses the cloud encoder

No data is sent to external servers during free local conversion. When the Cloud API is used, images are transmitted over TLS 1.2+, processed in-memory, and deleted immediately after conversion. Nothing is stored.

Administrators may configure a custom AVIF API endpoint in the plugin settings. When a custom endpoint is configured, image data and the API key are transmitted to that endpoint instead of api.picqlo.com. Custom endpoints must use HTTPS; the plugin rejects HTTP and private/internal addresses.

Privacy Policy

When the Cloud API is used, source images are transmitted to api.picqlo.com over TLS 1.2+. Images are processed in-memory and deleted immediately after conversion — nothing is stored. No data is sent to external servers during free local conversion.
