Convert BMP to WebP
BMP stores pixels raw — no compression at all. A single BMP screenshot can be tens of megabytes. Converting to WebP removes that waste entirely, shrinking files by 90% or more with no visible difference. It is the easiest optimisation you will ever make.
Usage Scenarios
- Cleaning up decades-old legacy document scans stored as BMP
- Publishing archival screenshots and diagrams that were saved in the default Paint format
- Reducing storage costs for image libraries that accumulated BMP files over time
Tips
- ▸Expect a 90-95% file size reduction in most cases — BMP is truly uncompressed
- ▸Use lossless WebP if you need guaranteed pixel-perfect reproduction (art, medical imaging)
- ▸BMP files do not carry EXIF metadata; consider adding titles and descriptions after conversion
