Convert WebP to BMP Online — Free
Runs 100% in your browser — your files never leave your device.
WebP is where the web lives; BMP is where some legacy systems refuse to leave. Bridge the two in one click: the WebP is decoded and written out as a 24-bit bitmap, locally in your browser. Transparency flattens, since BMP has no alpha.

Save the BMP with one click, or drop another file to convert it.
About this tool
Converting WebP to BMP
A WebP file webp is the modern web format: smaller than jpg at equal quality, and it supports both lossy and lossless modes plus transparency. BMP bmp stores pixels essentially uncompressed — enormous files, zero quality loss, and roots deep in legacy windows software that only accepts it.. Converting moves your image from the first set of trade-offs to the second: expect the file to grow substantially, transparency is lost, because BMP cannot carry it, and pixel data is re-mapped to the target format exactly.
What to check after converting
Open the result and check the two things conversion can change: transparency and size. Your WebP source supported transparency, which BMP cannot carry — transparent areas typically fill with white or black, so design around a solid background if that matters. Your original file stays untouched on your device either way, and the download is a brand-new file.
Frequently asked questions
Is this conversion lossless?
Yes — both WebP and BMP store pixels losslessly, so the conversion moves your image between formats without touching a single value. The file size changes; the pixels do not.
Is my image uploaded anywhere?
No — the conversion runs entirely in your browser. The image is processed on your device and never sent to any server, which you can verify by disconnecting after the page loads.
Why convert WebP to BMP instead of the other way around?
The direction follows what the destination needs: legacy Windows compatibility versus web performance. Converting back is always available — but each lossy hop re-encodes the image, so keep the highest-quality format as your working copy and convert toward the destination.
