It’s also nice that you can save an image directly to your Google Drive or DropBox without first downloading it to your computer. The interface is attractive and easy to use. While most images won’t get that sort of performance, Compressor is a good choice if you favor absolute file size over fine image detail. Compressor.ioĬompressor promises drastic file size reduction. The quality of the compressed PNG is almost identical to the original, which is why I love using the PNG format as much as possible because of its ability to be heavily compressed without as much loss in quality. There is some loss in quality, but the image still looks pretty good and your website will be more streamlined thanks to the optimization. Here is the JPG image after we released the kraken: In our test, Kraken reduced the size of our JPG image by about 15% (78 KB) and our PNG by about 61% (10 KB). You can also easily import images from Google Drive or Dropbox with a click. The free quick web interface doesn’t allow you to resize images or use other “Pro” features, but it is a simple drag and drop tool we could figure out in just a few seconds.īest of all, you can queue multiple files at once for quick batch processing. There are several paid tiers of the product, differing mainly by how many gigabytes of data you can process per month.
Kraken.io’s best feature is the fact that it gives us an excuse to yell “release the kraken!” every time we use it, but apart from that, it’s one of the fastest solutions we’ve tried and pretty simple to use. Here is our original JPG image (91 KB):Īnd here is our original PNG image (26 KB): PNG images are best suited for icons, text, screenshots of windows on your desktop, etc. JPG images are best suited for images of “real” people, places, things, etc. Sometimes you can compress your image a lot better if you save it using a different format. To show the difference that the file format makes in terms of compression, we used a JPG image and a PNG image.
