Convert BMP to WebP
Drop BMP files and download web-ready WebP at the same dimensions. An uncompressed bitmap is the wrong thing to ship to a page; WebP gives strong compression so the image loads quickly without looking degraded.
The encode is lossy, tuned for visual quality on the web. For an exact lossless copy, convert to PNG instead. For page assets, the size saving is the point.
When WebP helps
- Web publishing. Hero images, blog covers, and galleries load faster as WebP.
- Bandwidth. Lighter files cost less to deliver, especially on mobile.
- Folder cleanup. Converting old BMP exports standardizes them into a modern format.
Decoding note
Standard BMP files decode directly in the browser. Older or uncommon BMP variants are handled by a built-in decoder that loads once per tab the first time you convert one.
Batch and privacy
Add multiple files, convert, and use Download all as ZIP for the whole set. Conversion runs in your browser through Web Workers, in parallel; nothing is uploaded, and metadata is dropped when the image is re-encoded.
