Geek Flare Blog post is sponsored by Netsparker Web Application Security Scanner.

Optimize your WordPress, Joomla or any other website images to make your website load faster to boost search engine ranking.

Interesting stats by HTTP Archive shows average web page size is 2.4 MB and images contribute 64% of it.

That’s right, an average image size of a web page is 1.5 MB.


What’s your web page size?

If you have image an based website or it’s contributing factor, then you must optimize them to reduce the size. By reducing the image size, you get the following advantage.

  • Reduce web page size overall
  • Save bandwidth
  • Load your web page faster and eventually, help SEO ranking

There are multiple ways to optimize the images, but doing without losing quality is the smart way. In this article, I’ve covered three types of tools. 

  1. Standalone tools: You don’t need to install anything on your website. You can just visit the tool’s website and upload the images, and you will get optimized images to download.
  2. WordPress Plugin: You need to install the plugin in your WordPress website and based on settings, it will reduce the size whenever you upload the images.
  3. Joomla Extensions: You need to install extensions in Joomla website, and optimization will happen from your Joomla website server.

Standalone Tools

Using standalone tools are probably the best way to compress the images, but there will be limited either by size or number of images you can upload. So you got to try which one is best for you.

2. Compressor

Compress and reduce your image size up to 90% with Compressor while maintaining high-quality resolution. It supports JPEG, PNG, GIF & SVG and files size limit is 10 MB.

    Major difference between the package and the plugins and standalone tools in the articles is that image-optimize-command runs on your sever and it is smart enough to decide which tools to run with which kinds of images. Thus, no limitation on file size or month quota. Totally free of charge.

    However, it also means that it requires lots of server resource and a little bit of setup. Learn more from the introductory blog post about why I built it –
