BMP: what it’s for
BMP is Windows' raw bitmap: every pixel stored uncompressed, so files are enormous and the web ignores the format. Convert BMP to PNG (lossless, small) or JPG (photos) the moment one lands on your disk.
Strengths
- Dead simple — opens in MS Paint from 1995 onward
- Lossless pixels, trivially decoded anywhere
- Our tools read BMP locally and convert to PNG or JPG
- Useful as a zero-ambiguity interchange from old software
Honest limits
- No compression — routinely 10x larger than the same PNG
- No browser, phone gallery, or social support worth naming
- No animation, no real transparency story
- Never a delivery format — convert on sight

BMP FAQs
How do I convert BMP to PNG?
Use BMP to PNG — identical pixels at a tenth of the size, viewable everywhere. One click, local, free.
Why is my BMP so big?
BMP stores every pixel raw with no compression. PNG keeps the same pixels losslessly in a fraction of the space.
Should I ever keep BMP?
Only as a capture from legacy software. Convert to PNG immediately for storage and sharing.
Is BMP conversion private?
Completely. Conversion runs in your browser; files never upload.
