Supports BMP
Drop 24-bit or 32-bit BMP files. 32-bit BMP alpha channels preserve in WebP output.
Flat-color and graphic BMP uses lossless VP8L WebP. Photographic BMP uses lossy VP8 at quality 80. BMP has no decode overhead — fast conversion.
WebP files land at 5–10% of the original BMP size. Alpha preserved, ICC profile embedded, ready for any modern web pipeline.
