Does what it says. Compress images, simple, nothing extra nothing less. You can configure it to your needs (image quality, statistics, keep backups, etc) and it just works.

I usually don't write reviews, but I just wanted to write this one because this plugin has went beyond my expectations. I was having issues finding image compression plugins that worked and did what they were supposed to do, but this one has been outstanding! I have been using this on every website I build for a couple of years now and has never failed me. Thanks for the awesome work and keep it up!

Simple mais efficace. Attention cependant, le traitement ร  l'upload peut รชtre gรชnant en temps. Comme le fait de ne pas utiliser la Cron de WP. Merci beaucoup! --- Simple but effective. Beware, the optimization while when uploading can increase upload time too much for your use. Also, it doesn't support WP's cron. Thanks a lot!

Thank you for this amazing plugin, I'm a WordPress Developer and I install this plugin on every new website I make ๐Ÿ™‚ I have a personal photography blog, and it works like a charm. I can share my images, 1920px wide, in long blog posts without detroying my users bandwidth, I really appreciate that! Keep up the good work, and don't be depressed by those 1 star reviews, those guys just don't understand the principle of open source programing and free plugins... Have a nice day!

I've tried just about every compression tool out there, and unless you are willing to pay you barely get any compression at all. This tool is free, and the compression is quite good. The features are bare bones, but it is free and it works! Give the author time to let the plugin evolve, but I am happy with it just as it is.
