BMP to WebP converter
Convert BMP to WebP in your own browser tab. The picture is decoded and re-encoded here and is never uploaded.
Up to 20 images, 50.00 MB each. Output is WebP.
What this conversion changes
WebP is written at quality 92 and keeps transparency, so it is usually the smallest of the three destinations at the same visible quality. It is a lossy re-encode, so this is a second generation of loss on top of whatever the BMP already discarded.
Re-encoding does not carry EXIF across, so the camera settings and any location in the original are not written into the WebP file. Keep the original if you need them. The decoder is the one your browser already carries, so nothing is downloaded to do this.
The other conversions
Each has its own page, set to that pair when it opens.
