TA Tips – Best Image Compression Tools

Online visitors are incredibly impatient, so it’s important to keep your website optimized, fast and accessible to the masses. There are a plethora of tricks and tips for optimizing your site for peak performance, here are a few tools to help you solve one of the biggest problems for slow loading websites: Image Optimization.

Optimization images will make your files smaller without losing any resolution or quality. The smaller the file size, the faster it will make your website load faster for the user, whether they are on a desktop or mobile device. This will increase the user’s experience and decrease the client’s bandwidth leading to a better-optimized website.

While we list three different tools below, you could make the file size a little smaller by cropping them BEFORE you compress them. This is ideal if you are working with a higher resolution image like 3840×2160 and cropping them to 1280×720. The beauty of using these tools below is that you are able to change the compression percentages so you can find the optimal settings for your images.

ImageOptim (free for Mac) was able to reduce the sample image file size by 74.9% – 557kb.
ImageOptim is the free app that is great for lossless compression. All you have to do is drag a file/folder/group of images onto the interface and it’ll start compressing. The only downside is that ImageOptim overwrites your original file so you might want to save an extra copy before you start compressing.

Squash ($19.99 for Mac) was able to reduce the sample image file size by 54.5% – 1MB.
Though Squash may seem a little bit pricey at $19.99, it does a lot especially if you are dealing with multiple file formats. For example, Squash can convert and compress PSD, TIFF, and RAW files where ImageOptim does not.

Compressor (free web tool) was able to reduce the sample image file size by 64% – 801kb.
If you don’t want to download any more apps to your computer, you can use Compressor.IO to compress your images. It works just as great as Squash/ImageOptim and can support JPEG, PNG, GIF, and SVG files. The only downsides are that it doesn’t allow batch uploads and files are limited to 10 MB.

Caesium (free for Windows and web tool) was able to reduce the sample image file size by 60% – 885kb.
We didn’t forget about our Windows users! Caesium is a simple tool that compresses JPG, BMP, and PNG files. While the interface may not be as appealing like the other apps listed above, it does its job pretty well and is our go-to recommendation for anyone in the Windows environment.
