A freeemium easy to use, comprehensive, stable and frequently updated image optimization plugin supported by the friendly team that created it. :)

Increase your website's SEO ranking, number of visitors and ultimately your sales by optimizing any image or PDF document on your website. ShortPixel is an easy to use, lightweight, install-and-forget-about-it image optimization plugin that can compress all your past images and PDF documents with a single click. New images are automatically resized/rescaled and optimized on the fly, in the background.

This plugin uses minimal resources and works well with any shared, cloud, VPS or dedicated web hosting. It can optimize any image you have on your website even the images that aren't listed in Media Library like those in galleries like NextGEN or added directly via FTP!

Both lossy and lossless image compression is available for the most common image types (JPG, PNG, GIF and WebP) plus PDF files. Optimized images mean better user experience, better PageSpeed Insights or GTmetrix results, better Google PageRank and more visitors.
