JPG File Converter

JPG uses a lossy compression algorithm based on the Discrete Cosine Transform (DCT), which reduces file size by approximating image data. Images are divided into blocks, and data is compressed by removing less perceptible information. The compression level can be adjusted, allowing users to choose between higher quality or smaller file sizes.

JPG files support 24-bit color, enabling them to display millions of colors and capture detailed photographs. However, repeated editing and saving can degrade image quality due to its lossy compression method. This format became popular because it balances image quality and file size, which helped fuel the growth of digital photography.
