Often, most users upload images without any consideration of size or disk space. Uploading large images was not an issue until Google made page load speed a ranking factor. One of the best ways to improve both loading times and page speed is to optimize your images. Image optimization is also something that non-technical users can do with very minimal software. Here we look at several tools that you can use to optimize your post and site images.

Optimizilla

There are two advantages to using Optimizilla. The first advantage is a real-time preview that shows an approximation of how the image will look after optimization. You can use a slider to adjust the level of quality to a point you consider acceptable. Also, you can batch process up to 20 images at a time.

TinyPNG

The interface is a lot like Optimizilla and also processes 20 images in a single batch. The only difference is that you can export directly to a DropBox account.

Compressor.io

Not a great tool. It does the usual image compression but offers no batch conversion options. It is good enough if you want to convert a single image. However, when you plan to optimize an entire site, it will take too long.

Tests show that TinyPNG has the best compression ratio for roughly the same level of quality. The fact that it also processes images in batches of twenty makes it the best of the tools available for image compression.
