Compressify Image Optimizer helps you compress WordPress images, convert them to WebP or AVIF, and resize oversized uploads. Optimize new images automatically and process existing images in your media library in the background.
Smaller image files can reduce page weight and image transfer times. Compressify sends images to its external API for processing, so compression and conversion run outside your WordPress hosting environment.
Automatic image compression for new uploads
Enable automatic optimization to compress JPG, PNG, and WebP uploads without manually exporting each file. Choose an output format and adjust image quality to balance file size and appearance.
WebP and AVIF conversion
Convert supported images to WebP or AVIF, or keep a supported original format. Available output formats and usage limits depend on your Compressify plan. AVIF output requires a plan that includes it.
Bulk image optimization for your media library
Process images uploaded before you installed the plugin. Start a background optimization run from the WordPress dashboard and review processing progress and file-size savings.
Resize oversized WordPress images
Set a maximum image width to resize large images during optimization. This can reduce unnecessary image data before it reaches visitors’ browsers.
Image performance and Core Web Vitals
Reducing image size can help pages load faster. When an image is the Largest Contentful Paint (LCP) element, a smaller file can help reduce its download time. Actual results depend on your images, theme, hosting, caching, and other page resources; compression alone does not guarantee a PageSpeed score or Core Web Vitals result.
