One of the most image formats using the web is JPEG, as it allows high compression without losing much quality. Despite this, not all JPGE files found are optimized in a balanced way to offer the smaller, which is why it is sometimes necessary to take the time to get a tool to do the job for us and give us the best image quality while reducing the space they occupy.


Compressor.io is one of my favorites, lets you compress and optimize your images easily from anywhere. Supports 4 types of formats: JPEG, PNG, GIF, and SVG; and has two types of compression: Lossless and Lossy , the first maintains the image fidelity as possible but results in a larger file size, and the second can result in a reduction of up to 90% of the size image but the image quality decreases a little more.


Very similar to Compressor.io, Kraken.io provides a web interface to optimize and compress images, but has some extra things that do not have I mentioned earlier if you pay a Pro account.
For users is available free compression tool for JPEG and PNG files, and you can choose between “Lossy” and “Lossless”, plus your image remains available for download for 12 hours.

An effect almost invisible, but it makes a big difference in size. TinyPNG alpha transparency retains your file completely. They contain an plugin to WordPress, and one for Photoshop.

TinyJPEG on the other hand, does the same but with JPEG files, as is expected, and is capable of reduce the file size by up to 70% without sacrificing quality naked view.
