Kraken allows you to optimize not just JPEG, but PNG and GIFs as well. The lossy images will work just fine for most users, but professionals who wish to retain 100% visual information should opt for the lossless (e.g.

Lossy – a small drop in quality, but cuts down image file size by almost 90%.Kraken gives you a choice of compression modes: Once the tool compresses the image, you can download it and use it anywhere you need. And then go on to add effects like captions, borders or shadows. If you wish, you can also view EXIF data (time, date and camera make) and resize your images. Using just the default setting, I was able to cut down the file size by 66%. Most of us should be fine with the default compression of 65, though the website can compress images anywhere between 0-99. JPEG Optimizer is one of the first solutions to check out if all you need is to compress JPEG images. Now, let’s dig into the tools in more detail… 1. 10 million pixels means that if you email this image (or multiple photos) to a friend, the photo (which is a lot of space!) will save 30 million bytes (or 30 megabytes).*it lets you optimize manually afterwards When your camera or cell phone says it takes 10-megapixel photos, it means that each photo has 10 million pixels (megapixels). When an image is large, it can contain millions of pixels, meaning an image can take millions of bytes to store all the information on a computer or device.

Usually, 3 bytes (24 one or zero) are used to store each of these pixels. Images are made up of several points called pixels, each of which has a color that is represented as a combination of three primary colors (red, green, and blue).
