What It Does

Converter for Media converts existing JPEG and PNG images on your WordPress site into next-generation WebP and AVIF formats, which are smaller in file size and load faster. It then automatically serves these lighter versions to visitors whose browsers support them, while falling back to originals elsewhere. The plugin also handles bulk conversion of your existing media library, not just new uploads.

Who It's For

This plugin is best for site owners running image-heavy properties such as photography portfolios, real estate listings, travel blogs, e-commerce stores with product galleries, and news publishers where image weight directly affects load times and SEO. It fits well for anyone already on LiteSpeed or with server-level WebP support who wants a no-cost path to next-gen image delivery without paying for a SaaS image optimizer.

Who Should Skip It

If your site has very few images (under a few dozen) or you are already paying for an all-in-one image CDN service like ShortPixel or Optimole, this plugin adds little value. Users on shared hosting without GD or Imagick support, or those running older PHP versions, should also skip it since PHP 7.4+ is required.

The Bottom Line

Converter for Media scores 87.72/100 and delivers reliable WebP and AVIF conversion with near-perfect user ratings, very fresh maintenance, and a healthy install base. The weak spot is its thin support footprint and the fact that competitors with 1 million installs may have richer integrations. For most image-heavy WordPress sites that want a free, focused next-gen image converter, it is a solid pick.

Pick Smush if you want a single plugin that handles compression, lazy loading, and WebP conversion from a brand with 1 million installs.

EWWW Image Optimizer 89/100

Pick EWWW if you prefer server-side compression you control directly, or if you have very large libraries already optimized in place.

Imagify Image Optimization: Optimize Images | Compress & Convert to WebP/AVIF 87/100

Pick Imagify if you want a polished interface backed by a dedicated optimization API and do not mind a tiered pricing model.

ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF 86/100

Pick ShortPixel if you want a generous free monthly quota plus built-in CDN delivery for converted images.

Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization 85/100

Pick Optimole if you want off-site image hosting with automatic resizing and a CDN included, rather than local conversion only.
