Want to improve your page load times? Image optimization is a great place to start! Columnist Tom Demers reviews five free image compression tools and notes their impact on page speed.

Optimizarea imaginii SEO

Improving page speed is something that is generally pretty easily understood by clients, and it positively impacts user experience and conversion as well as SEO.

The challenge, frequently, can be that some elements of improving page speed can require significant input from development resources (e.g., prioritizing visible content, eliminating render-blocking JavaScript or CSS).

But there’s one element of page speed optimization that even non-technical marketers and content creators can contribute to image optimization. As Kristine Schachinger points out in her excellent article on image optimization, resizing and compressing images can often be the easiest and highest-impact action for speeding up pages on your site.

In following chapters we present you top 5 image compression tools:

  1. Optimizilla

The biggest “pros” in Optimizilla’s favor are that the tool allows you to run up to 20 images through for compression at a time (a couple of the others on this list do as well) and that it has a great image preview feature which lets you dial up or down the “quality” of the photo.

  1. TinyPNG

Like Optimizilla, TinyPNG has a nice, simple interface and allows you to run up to 20 images at a time. It also has a convenient “export to Dropbox” option.

  1. Compressor.io

Compressor.io also offers compression. Unfortunately, there’s not a bulk upload feature here, so you have to upload one image at a time.

  1. Kraken

Kraken does allow you to upload multiple files. It also has some nice features, like allowing you to easily export files to Dropbox or import files from Box, Dropbox or Google drive. Additionally, Kraken allows for “advanced” customization, like altering quality and orientation and preserving metadata for your photos.

speed up your site

In conclusion, all those tools have a significant impact on image size. Once all site’s images are optimized, you will see the loading speed will increase, will be faster. Don’t you believe? Well, give a try!
