BMP to WEBP
Skipping PNG middlemen
If your pipeline dumps uncompressed BMP but production wants modern codecs, jumping straight to WebP saves a disk-heavy PNG intermediate while preserving crisp UI edges via lossless WebP when configured.
Encoder nuance
Photos embedded inside BMP may prefer lossy WebP; flat UI shots often prefer lossless—your deployment decides defaults. Fall back to BMP to JPG when stakeholders distrust WebP in email.
