Windows' plain bitmap: every pixel stored as it is, with no compression, so files are big and predictable. Paint, older Windows software and some machines and embedded displays still expect BMP. The usual 24-bit kind has no transparency; 32-bit can carry it.

The lossless format for screenshots, logos, icons and anything with text or sharp edges. PNG keeps every pixel exactly and has full transparency, so it's what editors and design tools trade in — but a photo as PNG is usually several times bigger than a JPG.
PNG Converter — convert PNG files to any format
You want BMPs — screenshots, icons, sprites, Paint drawings or exports from old software — in a lossless format the web, editors and documents handle, without losing a pixel.
Every opaque pixel is kept exactly. A 24-bit BMP's size is fixed by its pixels — about 35 MB for a 4032 × 3024 photo, 5.9 MB for a 1920 × 1080 screenshot — and the PNG compresses the same pixels without loss. Screenshots and drawings with flat colour shrink the most.
Nothing to set: PNG is lossless. Resize is there if you want fewer pixels, but keep sprites and pixel art at their original size so their edges stay crisp.
Every browser, editor, office suite, design tool and device — and, unlike BMP, web pages and most upload forms.
