In order for your pictures to look good on retina/hi-res devices the size of images used in today’s web design world are increasing all the time.
As the image size increase so does the file size, so in order to save some bandwidth it pays to compress your images as much as possible (without losing too much quality of course).
TinyJPG is here to help you do just that. Made by the team behind TinyPNG, TinyJPG works by analysing your uploaded images. Textures, patterns and colours are automatically identified. the encoder creates an optimally compressed JPEG file based on that information. The final result is compared with the original and fine-tuned.
There is also a developer API available that allows you to create compressed JPG and PNG files on the fly.
