BMP favors simplicity and uncompressed pixel storage. JPG favors small, universally compatible files for everyday sharing.

File size and compression
BMP typically stores pixel data uncompressed, producing large files. JPEG uses lossy compression with an adjustable quality setting, trading a little detail for much smaller files.
Compatibility and use cases
BMP is a legacy Windows format still produced by some scanners, printers, and older software, but it is rarely used for web sharing. JPG opens everywhere and is the standard choice for photos.
When to convert
Use /tools/bmp-to-jpg when you need to share, email, or publish a BMP image and want a much smaller file.
