DVMAGIC Local Image Conversion for AVIF and WebP

DVMAGIC Local Image Conversion for AVIF and WebP converts JPEG, PNG and GIF uploads to modern formats on your own server — and can batch-convert your existing Media Library.

Built by Auslander Studio for production WordPress sites we operate ourselves. Unlike SaaS optimizers, everything runs locally with no usage caps — full feature set, free.

What makes this plugin different

• No external API — images never leave your server
• No subscription or quota — batch the whole Media Library when you need to
• AVIF-first with WebP fallback when the host cannot encode AVIF
• Optional keep originals for rollback without a second plugin
• Server capability panel so you know what the host can encode before you batch
• URL rewrite in post content and meta after conversion

Features

• Convert on upload (optional)
• Batch convert legacy library images
• AVIF primary with automatic WebP fallback when the host lacks AVIF encode
• Optional Keep originals (off by default)
• Server capability panel (Imagick, GD, AVIF/WebP)
• URL rewrite in post content and meta after conversion
• Action Scheduler queue when available; WP-Cron fallback

Requirements

• AVIF encoding: PHP extension imagick (PECL imagick) with ImageMagick built for AVIF output (AVIF in Imagick::queryFormats('AVIF')). GD cannot encode AVIF in this plugin.
• WebP encoding: imagick with WebP support, or PHP extension gd with WebP enabled (imagewebp available).
• Sufficient disk space and CPU for batch jobs
• Back up wp-content/uploads/ before running a full library batch

Check Media → DVMAGIC Image Conversion → Server capabilities after install — the panel shows Imagick, Imagick WebP, Imagick AVIF, and GD WebP on your host.

PHP extensions (summary)

• AVIF output — PHP extension imagick (PECL). ImageMagick on the server must support AVIF encode (host-dependent; often ImageMagick 7 + libavif). Check “Imagick AVIF” in the plugin’s Server capabilities panel.
• WebP output — imagick with WebP support, or PHP extension gd with WebP enabled (imagewebp).
• Reading JPEG/PNG/GIF — imagick and/or gd (typical on most hosts).

If only GD with WebP is available, set Primary format to WebP, or leave AVIF and the plugin will fall back to WebP when AVIF encode is not detected.
