Why use this converter?
Key details about this conversion path.
Adjustable lossy output quality
Higher percentage values generally retain more detail and produce larger files; lower values favor smaller lossy output.
Content-dependent file size
The final size may be similar, larger, or smaller depending on the source content and selected settings.
BMP input and configured WebP output
BMP input is decoded for the configured pipeline. The image pipeline writes a quality-controlled lossy still WebP; it does not use WebP lossless mode or preserve animation.

Frequently asked questions
Details about this conversion and its output.
No. BMP can use different bitmap encodings, so this source is treated as codec-dependent rather than assumed to be uncompressed.
Transparent source pixels are composited against white; the output does not retain an alpha channel.
This configured output uses lossy compression.
Higher percentage values generally retain more detail and produce larger files; lower values favor smaller lossy output.
The final size may be similar, larger, or smaller depending on the source content and selected settings.
The image pipeline writes a quality-controlled lossy still WebP; it does not use WebP lossless mode or preserve animation.
