What It Does

Plus WebP or AVIF automatically converts uploaded JPEG and PNG images into the WebP or AVIF format at upload time, serving smaller next-generation images to visitors without changing the original files. It uses server-side libraries to handle the conversion process on the fly, which means no third-party API or ongoing service fees. The plugin targets users who want to reduce image payload on their WordPress site without managing external image optimization services.

Who It's For

This plugin is a strong fit for site owners running their own VPS or managed hosting where they have full control over PHP extensions like GD or Imagick and can install the cwebp or avifenc encoders. It suits performance-focused blogs, portfolios, e-commerce sites, and small-to-medium publications that are comfortable verifying server-side conversion dependencies themselves. Developers and agencies that want a lightweight, no-subscription image format converter will likely appreciate its minimal footprint.

Who Should Skip It

If your host restricts shell commands or you cannot install command-line encoders, skip this plugin because WebP and AVIF conversion typically relies on cwebp or avifenc binaries that not all shared hosts allow. Users looking for a fully managed, codeless experience with built-in CDN delivery should look at Optimole or Shortpixel rather than debugging server binaries.

The Bottom Line

Plus WebP or AVIF scores a respectable 77.87/100 with strong maintenance, perfect compatibility scoring, and highly favourable user ratings, but limited adoption and zero tracked support threads mean you are trusting a smaller project. It is a competent option for technically comfortable users with the right server environment, yet most WordPress site owners will find better-supported and more widely deployed alternatives in the same category. Treat it as a capable niche tool rather than a default recommendation.
