About BMP to WebP
WebP is a modern image format that compresses better than JPG and PNG. Converting a BMP to WebP replaces its uncompressed pixel grid with efficient lossy or lossless encoding, cutting file size by 50% or more while preserving visual quality.
This tool converts BMP files to WebP directly in your browser. Your images never leave your device — the conversion runs locally using the Canvas API. No upload queue, no server processing, no privacy risk.
Output matches the original in resolution and color, but at a fraction of the file size. Every modern browser supports WebP natively — no plugin needed, no watermark, no limit.

What is WebP format?
WebP is a modern image format developed by Google. It supports both lossy and lossless compression and typically delivers 25-35% smaller files than JPG at the same visual quality.
