ShortPixel
ShortPixel is a powerful image optimization plugin and API service designed to reduce image file sizes without noticeable loss in quality.
Our take: ShortPixel compresses JPG, PNG, GIF, WebP, AVIF, and PDF files via a cloud API and a best-in-class WordPress plugin.
The go-to image optimizer for WordPress sites — generous unlimited plan at $9.99/mo beats most per-image alternatives hands-down.
