Compressing BMP to Under 100 KB
At 100 KB the BMP is converted to WebP or JPEG at standard web quality. Because the source is uncompressed, this target is easy to hit while keeping good visual quality. Use it for general web imagery originating from BMP, such as scanned or exported graphics. Dimensions up to about 1920 px are retained. The dramatic size reduction comes from modern compression, not from discarding meaningful detail.

Frequently Asked Questions
Can I get a lossless result from a BMP under 100 KB?
Often yes — WebP lossless can keep the BMP pixel-perfect while still being far smaller. For photographic BMPs, lossy WebP/JPEG looks better per kilobyte.
Does BMP support transparency?
Rarely used. Most BMPs are opaque, so conversion to WebP/JPEG is straightforward. If alpha exists, WebP preserves it; JPEG does not.
