Theres a few different ways of compressing an image into a JPEG format. Have a look at IJL (Intels JPEG Library) or check out the Joint Photography Experts Group homepage.

Just so you know:
If you compress an image to JPEG, there is NO recovery back to BMP. Whats lost during the compression is lost. Its got to do with the way they subsample in their compress algorithms.

Try use imageviewer cp activex control that can convert file format!

As far as I'm concerned the facts are facts, you convert an image to jpg and then back to bmp, you end up with a crappy looking bmp file.

You have been warned.

For compressing images into JPEG, libraries like IJL work well, but remember, quality is lost during compression, so there is effective solution without coding, you could try an online JPEG compressor tool.

To compress an image into JPEG and decompress it, you can use various tools and libraries. For Python, Pillow is a great option that allows you to easily compress images by adjusting the quality. For web-based solutions, tools like TinyPNG or JPEG-Optimizer are perfect for quick, hassle-free compression. These methods make it simple to compress or decompress images without needing complex setups.
