When you convert a WebP image to BMP (Bitmap) format, the following occurs:
When you need uncompressed quality, maximum compatibility with editing software, or are working with systems that don't support WebP.
Significantly larger - BMP is uncompressed while WebP uses advanced compression.
It prevents further quality loss but cannot restore quality already lost in WebP compression.
BMP supports transparency in newer versions, but many applications treat it as opaque. Transparency may be converted to a solid background color.
Only single frames can be converted - BMP doesn't support animation.
Typically 24-bit (16 million colors) or 32-bit (with alpha channel) depending on the original WebP.
Most standard metadata is preserved, but some WebP-specific metadata may be lost.
Both can be equally accurate, but BMP guarantees no compression artifacts.
