Why convert BMP to JPG?

BMP (Bitmap) — Uncompressed Microsoft format. Very large files, rarely used on the web. Often encountered in legacy Windows contexts.

JPG (JPEG (Joint Photographic Experts Group)) — The most-used lossy format on the web. Excellent quality/size ratio for natural photos, but doesn't support transparency.

Converting BMP to JPG typically reduces file size while preserving a visual quality close to the original. This conversion significantly cuts file size — ideal for the web.
