Photos and images take up a big part of many websites today. In fact, you’d be hard-pressed to find a site without any photos at all! Aesthetic as they may be, they also take up a huge space on your server. The trick then, is to compress them so they load fast, without compromising on quality.
Why compress images?
The main reason to compress your photos is so they load quickly with your website. As of 2018, Google has announced that it will count the speed of how fast a landing page loads as a ranking signal for both desktop and mobile.
If you think about it, it’s a win-win strategy. On one hand, users get the best experience when exploring your site because it loads fast. And on the other hand, you get less site abandonment due to slow loading speed. To gauge how well your website is doing, you can visit PageSpeed Insights for a quick test.
There’s no shortage of image compressor tools or image optimizers on the Web. If you’re running your blog or website on WordPress, there are also handy plugins to help you do the work automatically. But what if you’re not?
Don’t worry, this collection of the best image compression tools will work on just about any platform, from BlogSpot, Tumblr, to Wix.
