Compress Jpeg is a free online tool that can reduce the size of any image. It works by removing bits of information from the image to reduce file size without reducing quality. This is called lossy compression. The other type of compression is known as lossless. Lossless compression keeps the original image data, but it takes up more space than a smaller version of the same image.

Despite being more than 5 “forevers” old, the JPEG standard is still going strong and is used on a huge range of devices, including mobile phones, digital cameras, TVs, and DVDs. This is because it is a very useful compression format and because it allows for very high-quality images to be stored in relatively small files.

Small Size, Big Impact: The Advantages of Using Compress JPEG for Web Images

A JPEG image is compressed by converting it to the frequency domain, throwing away some of the color information, and then using transform coding to compress the remaining data. The key is that the coefficients in the transform coding are quantized, which means that they have to be reduced to very small numbers that can be stored. This is done by ensuring that the lowest-frequency coefficients appear first and that the highest-frequency coefficients appear last.

The other main advantage of a JPEG is that it can be resized without losing any quality, which is very useful for sharing photos and images via email, social media or websites. This is because the pixel data in the image is encoded as integers (base 2) instead of binary values (bits). This makes it very easy to reduce the size of an image without any noticeable loss of detail, or artifacts.
