WordPress 7.1 Adds Client-Side Image Processing But Skips True Optimization
WordPress 7.1 introduces client-side media processing, using a WebAssembly tool called wasm-vips to handle image compression and thumbnail generation in the browser before files reach the server. This change addresses a longstanding issue where large image uploads would exceed server memory limits or time out, particularly on shared hosting. However, the feature applies a single fixed quality setting to all new uploads and does not affect images already in the Media Library. It also lacks automatic WebP or AVIF format delivery, CDN support, and per-image quality analysis. Users who need comprehensive image optimization for page speed performance will still require a dedicated third-party plugin.
