Optimizing images & using a CDN has become essential for online publishing.
A few days back, I talked about the best image compression WordPress plugins where I highlighted some great solutions for compressing images on your blog.
But not everyone is using the WordPress platform for their website. Many of us are blogging on various other platforms like BlogSpot, Tumblr, or something else.
What’s the best image compression solution for these users?
Well, this is where online image compression tools come into the picture.
When you search online for photo compressor tools, you will be awestruck by the sheer number of tools available. To make your work easier and save you some time, I’m listing some of my favorite tools that you can use right now to compress images & make them web-ready.

Question: Why do you need to compress images?
The main reason is to lower down the loading time of your blog as this has a direct correlation with search engine ranking.
If your page takes more time to load, your competitor can outrank you based on similar quality content, but a faster loading time.
It’s important to note that having images on our blog posts are very useful as they improve the visual experience & make our content more media rich.
At the same time, to stop images from slowing down the loading time of our pages, we can use a few techniques:
- Compress images without losing quality.***
- Use high-quality hosting for your website.
- Use a Content Delivery Network.
- I recommend using MaxCDN with a WordPress blog.
When in doubt, you can use any of these page loading time testing tools to see how fast or slow your website is loading.
