Is BMP to PNG conversion lossless?

Completely — PNG compresses the exact same pixels losslessly, typically shrinking the file by 50–90% with zero visual change. It's one of the few conversions with no trade-off at all.

Why choose PNG over JPG when converting BMP?

PNG keeps every pixel exact, which matters for the screenshots, scans, and graphics that usually live in BMP files. Pick JPG only when the BMP contains a photograph and you want the smallest possible file.

Is there any reason to keep files in BMP format?

Practically none today — BMP's only virtue is simplicity, and PNG matches its quality at a fraction of the size. Converting a folder of old BMPs to PNG loses nothing.
