Jpeg compression Tool

If you are looking to Compress your Jpeg or Jpg Image then "rankimg" also provide the best jpeg compression tool that can compress jpeg image upto 80% without Quality Loss.

A jpeg is nothing more than an uncompressed raw file that has already been saved from your camera. This means you can actually save a lot of space with a very low quality picture by compressing it before saving.


The jpeg compression algorithm uses a process called Discrete Cosine Transform (DCT) on the source picture that converts it into a grid of 8x8 pixel blocks. These blocks are then run through a quantization algorithm which rearranges the pixel values and chooses the best way to assign them to the 8x8 block without losing too much information. To put this another way, the quantization process removes unimportant data by rounding pixel values down to the nearest allowed value.
