Sali Media Optimizer

Sali Media Optimizer is a lightweight, all-in-one media converter and compression plugin. Acting as a high-performance WebP converter and WebM converter, it automatically converts image uploads to WebP or AVIF, and video uploads to WebM. It reduces file sizes by up to 80% with zero visible quality loss, optimizing your WordPress media library for speed and SEO.

Key Features

• Automatic Conversion: Converts newly uploaded images to WebP/AVIF and video uploads (MP4/MOV/AVI) to WebM.
• Auto-Resize on Upload: Set maximum dimensions (e.g. 2048px) to automatically downscale huge camera images before compression.
• Performance Benchmark: Diagnostic benchmark tool to measure local compression speeds of PHP GD, Imagick, and cloud fallback.
• CDN URL Rewriter: Rewrite frontend asset domains to bunnycdn, cloudflare, or bunny.net.

• Background WP-Cron Sync: Bulk optimize your pre-existing media assets periodically in the background.
