Why use this converter?
Key details about this conversion path.
Broader PNG compatibility
BMP has modern browser support, while PNG has universal support.
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 PNG output
BMP input is decoded for the configured pipeline. The image pipeline writes a standard lossless still PNG rather than an animated APNG.
Controls for this operation
This tool exposes Compression Level settings before processing.

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 lossless compression.
The final size may be similar, larger, or smaller depending on the source content and selected settings.
The image pipeline writes a standard lossless still PNG rather than an animated APNG.
