BMP is Windows' original uncompressed bitmap — lossless by default, huge by design. Convert from BMP to modern formats that ship the same pixels in a fraction of the bytes.

Drop BMP files to convert out; or drop PNG/JPG/WebP to convert into BMP for tools that require it.
BMP is raw pixel data — fastest decode of any format. Output encodes to your chosen format in-browser using the appropriate codec.
BMP to JPG: 90–95% size reduction. BMP to PNG: lossless, 40–70% smaller. BMP to WebP: 90–95% smaller. Alpha preserved for 32-bit BMP sources.

BMP stores every pixel as raw RGB bytes — no codec, no loss, no compression. That's fine for data integrity and terrible for file size. Every modern format outcompresses it by 10–20×.
