BMP to WebP converter
Drop one or more BMP files and download them as WebP. The conversion runs entirely in your browser: no upload, no queue, no account, no watermark.

or pick them from your device: several at once is fine
Files never leave your device: this page has no server to send them to.
How it works
Your browser decodes the BMP file, redraws it on a canvas, and re-encodes the pixels as WebP. Converting to JPG flattens transparency onto a white background, and SVG files are rasterized at twice their nominal size so edges stay sharp.
Frequently asked questions
Is this converter really free and private?
Yes. The conversion happens inside your browser using its built-in image engine. Nothing is uploaded, so there is nothing for a server to keep, and there is no account, limit or watermark.
What happens to transparency?
PNG and WebP keep transparent backgrounds. JPG has no transparency, so transparent areas are flattened onto white during conversion.
Why convert BMP to WebP?
WebP is often the format a form, tool or platform actually accepts. Converting locally gets you a compatible file in seconds without trusting a third-party uploader.
