What happens when using jpeg as the format for optimizing images?

When using jpeg as the format for optimizing images, the higher the image quality percentage value, the larger the file size.

JPEG (Joint Photographic Experts Group) is the product of the JPEG standard, which was formulated by the International Organization for Standardization (ISO) and is a compression standard for continuous-tone still images. JPEG format is the most commonly used image file format, with the suffix .jpg or .jpeg.

JPEG performance, measured by the ratio of quality to bitrate, is quite superior.

Its advantages are:

It supports extremely high compression rates, so the download speed of JPEG images is greatly accelerated.

It can handle 16.8M colors easily and can reproduce full-color images well.

This image format allows you to freely choose between the smallest file size (lowest image quality) and the largest file size (highest image quality) during the image compression process.

The file size of this format is relatively small and the download speed is fast, which is conducive to transmission when the bandwidth is not "rich".
