BMP vs WebP: what changes

BMP WebP
Type Raster (pixels) Raster (pixels)
Compression Uncompressed Lossy or lossless
Transparency No Yes
Animation No Yes

BMP is an uncompressed Windows bitmap that stores every pixel raw. That keeps it perfectly lossless but produces very large files — often ten or more times the size of an equivalent PNG.

WebP is a modern raster format from Google that does both lossy and lossless compression, supports transparency and animation, and runs about 25–34% smaller than JPEG at the same visual quality (per Google's own compression study).

WebP supports transparency, though a BMP has none to carry over — the image simply stays fully opaque. At matching quality WebP typically lands about 25–34% smaller than an equivalent JPEG.

When to convert BMP to WebP

Converting BMP to WebP turns a massive uncompressed bitmap into a compact modern web file, with the option of lossless mode if you want to keep every pixel.

Good to know: A few older desktop apps still won't preview WebP, though every current browser will.
